Description

{Tube-Type Spectroscopic Analysis System for Blocking the External Environment}

The present invention relates to a spectroscopic analysis system, and more specifically, to a spectroscopic analysis system formed in a tube shape and capable of efficiently controlling an internal sealed space by blocking the external environment.

In general, the optical system for an experiment can be configured differently even for the same experiment depending on the researcher's research direction, goal, and experimental environment. Among them, the optical system for spectral analysis requires variable control to measure the characteristics of a sample or specimen, and one of the variables that accounts for the largest portion is the atmospheric environment.

In other words, in order to obtain precise experimental results, the temperature and humidity must be controlled consistently according to the characteristics of the optical system and the characteristics of the sample or specimen, and in some cases, an inert gas must be supplied.

In this way, optical components are being developed and used to control the atmospheric environment, and among them, lens barrels are mainly used as optical components such as lenses or detectors, and their main purpose is to block light coming from outside.

However, although conventional optical paths are effective in blocking light coming from outside the optical path, their scope of use is extremely limited, and there is a problem in that it is impossible to control the environment along the optical path in an environment blocked from the outside.

In addition, when using a parabolic mirror among various optical components, a box-shaped case is often used to create an environment blocked from the outside because the parabolic mirror is larger than other mirrors or lenses due to its characteristics.

Since a box-shaped case like this must have a form that encloses all the optical systems, a large amount of inert gas must be supplied to create an internal environment suitable for the experiment, and there is also the problem that the inert gas filling process takes a long time.

Therefore, a method to solve these problems is required.

The present invention is an invention devised to solve the problems of the above-described prior art, and has the purpose of providing a spectroscopic analysis system formed in a tube shape to protect an optical system from the external environment and to more effectively construct an optical experimental environment.

The tasks of the present invention are not limited to the tasks mentioned above, and other tasks not mentioned will be clearly understood by those skilled in the art from the description below.

In order to achieve the above object, the present invention provides a tube-type spectroscopic analysis system for blocking an external environment, in which a plurality of unit units formed in a tube shape with a hollow formed inside are connected to each other to form a sealed space and form a preset optical path, the tube-type spectroscopic analysis system including: a mounting unit configured to allow an optical specimen to be placed inside and positioned on the optical path; a plurality of optical refraction units, at least one of which is provided in each of a light entry direction and a light exit direction based on the mounting unit and having a parabolic mirror provided inside to refract the optical path; a light entry unit connected to a light refraction unit provided on a light entry direction side among the plurality of optical refraction units and having a first lens for allowing light to enter from the outside to the inside; and a light exit unit connected to a light refraction unit provided on a light exit direction side among the plurality of optical refraction units and having a second lens for allowing light to exit from the inside to the outside; and at least one of the plurality of unit units has a gas injection unit formed inside the sealed space for injecting an inert gas.

In addition, the present invention may further include a first connecting unit provided between the mounting unit and the light refraction unit to connect the mounting unit and the light refraction unit to each other.

And the present invention may further include a second connecting unit provided between at least one of the light refraction unit and the light entry unit and between the light refraction unit and the light exit unit, and connecting the light refraction unit and the light entry unit, or the light refraction unit and the light exit unit.

In addition, the light refraction unit is provided in multiple numbers in each of the light entry direction and the light exit direction based on the mounting unit, and in this case, the present invention may further include a pair of third connection units provided between a pair of light refraction units adjacent to each other in the light entry direction or the light exit direction and individually connected to the corresponding light refraction units, and a tab unit provided between the pair of third connection units and mutually fixing the pair of third connection units.

Here, the opposite ends of the pair of third connecting units are formed with protrusions protruding outwardly from the periphery of the third connecting unit, and the tab unit includes a pair of clamp members that are divided from each other, and a fixing groove into which each protrusion of the pair of third connecting units is inserted is formed on the inner side of the clamp members, so that the pair of third connecting units can be fixed by mutual coupling of the pair of clamp members.

And the third connecting unit can be formed in a plurality of specifications with different lengths so as to be interchangeable.

Meanwhile, a specimen loading hole having a portion of an opening around the circumference is formed at a predetermined position of the mounting unit so that the optical specimen can be loaded. In this case, a cover member that selectively shields the specimen loading hole may be further included.

At this time, the cover member can be formed to be magnetically coupled to the mounting unit.

Additionally, one or more sunken gas flow grooves may be formed on the inner side of the cover member to allow an inert gas to flow to the outside of the optical specimen loaded into the mounting unit.

And the light refraction unit may include a mirror receiving portion in which the parabolic mirror is received inside, and a light conducting portion connected at a preset angle to the mirror receiving portion in consideration of the angle of the reflection surface of the parabolic mirror.

Here, a light passage hole may be formed in a parabolic mirror provided in some of the light refraction units among the plurality of light refraction units, and in this case, a light inlet section for introducing light from the outside toward the light passage hole may be further formed in the mirror receiving section of the light refraction unit provided with the parabolic mirror in which the light passage hole is formed.

The effects of the present invention are not limited to the effects mentioned above, and other effects not mentioned will be clearly understood by those skilled in the art from the description of the claims.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 and FIG. 2 are drawings showing the overall structure of a tube-type spectroscopic analysis system according to one embodiment of the present invention.

As illustrated in FIGS. 1 and 2, a tube-type spectroscopic analysis system according to one embodiment of the present invention has a plurality of unit units formed in a tube shape with a hollow space formed on the inside, which are connected to each other to form a sealed space that is entirely connected, and this sealed space forms a preset optical path.

At this time, at least one of the plurality of unit units may be formed with a gas injection unit for injecting an inert gas into the sealed space. The location of the gas injection unit is not limited to a specific location.

And the plurality of unit units can be classified according to their functions, and in the case of this embodiment, they are specifically composed of a mounting unit (100), a light refraction unit (200), a light entry unit (300), and a light exit unit (400).

The mounting unit (100) is a component that is provided so that an optical specimen (S) can be loaded inside and positioned on an optical path.

In addition, a plurality of light refraction units (200) are provided, and at least one may be provided in each of the light entry direction and light exit direction based on the mounting unit (100). In addition, a parabolic mirror (210) that refracts the light path is provided inside the light refraction unit (200).

In this embodiment, two light refraction units (200) are arranged on the light entry direction side with respect to the mounting unit (100) so that the light can reach the optical specimen (S) loaded into the mounting unit (100) by refraction of the optical path twice. In addition, two light refraction units (200) are arranged on the light exit direction side with respect to the mounting unit (100) so that the optical path after passing through the optical specimen (S) is refractioned twice.

In addition, the light entry unit (300) is connected to a light refraction unit (200) provided on the light entry direction side among a plurality of light refraction units (200), and is provided with a first lens that allows light to enter from the outside to the inside.

And the light exit unit (400) is connected to the light refraction unit (200) provided on the light exit direction side among the plurality of light refraction units (200), and is provided with a second lens that allows light to exit from the inside to the outside.

The arrangement form of each unit as described above is only presented as an example, and the number and connection form of each unit may of course be changed in various ways.

Meanwhile, in addition, the plurality of unit units in this embodiment further include a first connection unit (10), a second connection unit (20), a third connection unit (30), and a tap unit (40), which will be described later.

Below, each component that constitutes this embodiment will be described in more detail.

FIGS. 3 and 4 are drawings showing the structure of a mounting unit (100) in a tube-type spectroscopic analysis system according to one embodiment of the present invention.

As shown in FIGS. 3 and 4, in this embodiment, a specimen loading hole (110) having a portion of its circumference open is formed at a predetermined position of the mounting unit (100) so that an optical specimen (S) can be loaded.

At this time, in the present embodiment, a cover member (150) that selectively shields the specimen loading hole (110) of the mounting unit (100) may be further included.

In particular, in this embodiment, the cover member (150) may have a form that can be magnetically coupled to the mounting unit (100).

Specifically, in the present embodiment, a plurality of magnetic members (160) are provided in a protruding form at the bottom of the cover member (150), and a magnetic coupling groove (120) into which the magnetic members (160) are inserted is formed in the mounting unit (100). At this time, the mounting unit (100) itself can be formed of a magnetic material that can be attached to the magnetic members (160) by magnetic force, and thus the cover member (150) can be formed so that it can be easily detached with minimal force.

However, it goes without saying that the mounting unit (100) may be formed of a non-magnetic material, and in such a case, the magnetic material may be partially provided only in the magnetic coupling groove (120) portion.

The reason why the cover member (150) is applied in a magnetic bonding form is that the present invention is an optical experiment device, and if excessive physical force is applied, the path of light may become distorted. Therefore, by applying a method of bonding the cover member (150) using magnetic force, the application of physical force can be minimized.

However, it is obvious that the method of combining the cover member (150) and the mounting unit (100) is not limited to this embodiment.

In addition, one or more sunken gas flow grooves (151) may be formed on the inside of the cover member (150) so that an inert gas can flow to the outside of the optical specimen (S) loaded into the mounting unit (100) within the sealed space. This is to prevent the inert gas from flowing between the light ingress direction and the light egress direction by completely shielding the cross-section of the sealed space with the optical specimen (S).

In addition, it goes without saying that a gas flow groove (151) like this can also be formed on the mounting unit (100) side.

FIG. 5 is a drawing showing the structure of a light refraction unit (200) in a tube-type spectroscopic analysis system according to one embodiment of the present invention.

As illustrated in FIG. 5, the light refraction unit (200) in this embodiment has a form including a mirror receiving portion (220) in which a parabolic mirror (210) is received inside, and a light propagation portion (230) connected to the mirror receiving portion (220) at a preset angle in consideration of the reflection surface angle of the parabolic mirror (210).

In the present embodiment, the light propagation unit (230) is connected at a right angle to the mirror receiving unit (220), but the angle formed by the light propagation unit (230) with respect to the mirror receiving unit (220) is not limited to a specific angle.

Additionally, a light passage hole (211, see FIG. 2) may be formed in a parabolic mirror (210) provided in some of the light refraction units (200) among the plurality of light refraction units (200).

In addition, in the mirror receiving portion (220) of the light refractive unit (200) equipped with a parabolic mirror (210) in which a light passage hole (211) is formed in this manner, a light inlet portion (240, see FIG. 1) that introduces light from the outside toward the light passage hole (211) can be further formed, thereby allowing additional light to be introduced from the outside.

Meanwhile, as described above, the plurality of unit units in the present embodiment may further include a first connection unit (10), a second connection unit (20), a third connection unit (30), and a tab unit (40), which are provided for the purpose of connecting any one pair of the mounting unit (100), the plurality of light refraction units (200), and the light entry units (300) to each other.

FIG. 6 is a drawing showing a connection structure by a first connection unit (10) in a tube-type spectroscopic analysis system according to one embodiment of the present invention.

As shown in Fig. 6, the first connection unit (10) is provided between the mounting unit (100) and the light refraction unit (200), and serves to connect the mounting unit (100) and the light refraction unit (200) to each other.

That is, the first connection unit (10) is provided in pairs on both sides centered on the mounting unit (100) and is provided to connect the light refraction units (200) located on both sides of the mounting unit (100).

At this time, the first connection unit (10) and the counterpart unit connected to the first connection unit (10) may have a rotational connection/separation structure by screw threads, and this is not limited to the present embodiment as one of various connection methods is adopted.

FIG. 7 is a drawing showing a connection structure by a second connection unit (20) in a tube-type spectroscopic analysis system according to one embodiment of the present invention.

As illustrated in FIG. 7, the second connection unit (20) is provided between at least one of the light refraction unit (200) and the light entry unit (300), and between the light refraction unit (200) and the light exit unit (400), and serves to connect the light refraction unit (200) and the light entry unit (300), or the light refraction unit (200) and the light exit unit (400).

In Fig. 7, the connection structure of the light refraction unit (200) and the light entry unit (300) is representatively illustrated, but it goes without saying that this structure can be equally applied to the light refraction unit (200) and the light exit unit (400).

In addition, the second connecting unit (20), like the first connecting unit (10), may have a rotational coupling/separation structure with the unit to which it is connected by screw threads.

FIG. 8 is a drawing showing a connection structure by a third connection unit (30) and a tap unit (40) in a tube-type spectroscopic analysis system according to one embodiment of the present invention.

As illustrated in Fig. 7, the third connection unit (30) is provided between a pair of light refraction units (200) adjacent to each other in the light entry direction or light exit direction based on the mounting unit (100), and is individually connected to each corresponding light refraction unit (200). That is, a pair of third connection units (30) may be provided in each of the light entry direction or light exit direction.

This third connection unit (30) can also have a rotational coupling/separation structure with the optical refraction unit (200) to which it is connected, similar to the first connection unit (10) and the second connection unit (20), through screw threads.

And the tab unit (40) is provided between a pair of third connection units (30) and serves to mutually fix the pair of third connection units (30). At this time, the fixing method of the pair of third connection units (30) by the tab unit (40) can be implemented in various ways.

In the present embodiment, a protrusion (31) protruding outward from the circumference of the third connecting unit (30) is formed at the opposite ends of a pair of third connecting units (30).

At this time, the tab unit (40) includes a pair of clamp members (41) that are formed in a mutually split form so as to be mutually coupled/separated. Specifically, each clamp member (41) includes a fastening wing portion (42) that is formed to protrude in both directions so as to be in mutually surface contact, and thus can be mutually fastened by a separate fastening member.

And, on the inside of each clamp member (41), a fixing groove (43) is formed into which each protrusion (31) of a pair of third connection units (30) is inserted, so that when a pair of clamp members (41) are mutually coupled, a pair of third connection units can have a form in which they are fixed by the tab unit (40).

Meanwhile, in the case of this embodiment, a gas injection unit (50) for injecting an inert gas such as nitrogen gas into the inside of a sealed space is provided in a tab unit (40) positioned in the direction of light entry.

In addition, a gas discharge portion (not shown) for discharging gas to the outside may be formed in the tap unit (40) positioned in the direction of light advancement, but this is not limited to the present embodiment.

Meanwhile, FIG. 9 is a drawing showing the appearance of a third connection unit (30) having various specifications in a tube-type spectroscopic analysis system according to one embodiment of the present invention.

As shown in Fig. 9, in this embodiment, the third connection unit (30) is provided in multiple specifications with different lengths (d1, d2, ...) and can be formed to be interchangeable. This is to enable the total length of the optical path to be changed in various ways so that various experiments can be conducted.

As described above, the present invention forms a sealed space by connecting multiple unit units in a tube shape, and controls an optical system using a minimum space by forming a preset optical path, and can significantly reduce the amount of inert gas supplied to control the atmospheric environment of an internal sealed space blocked from the outside.

As a result, the present invention can reduce the time required for stabilizing the internal atmosphere, and can also reduce the amount of additional inert gas introduced.

In particular, when each unit of the present invention is formed of a metal material, light coming from the outside can be blocked, and when the inside and outside of each unit are formed in black, the reflection effect occurring in the internal sealed space can be minimized.

As described above, preferred embodiments according to the present invention have been examined, and it is obvious to those skilled in the art that the present invention can be embodied in other specific forms in addition to the embodiments described above without departing from the spirit or scope thereof. Therefore, the above-described embodiments should be considered as illustrative rather than restrictive, and accordingly, the present invention is not limited to the above description, but may be modified within the scope of the appended claims and their equivalents.
