Description

Detailed Description of the Invention

[0001]

The present invention relates to a plurality of light sources (ultraviolet rays, visible rays, infrared rays, laser rays, X-rays) for various samples.
(e.g., starting light such as e) is focused and irradiated at the same point to observe a sample.

[0002]

2. Description of the Related Art As a conventional irradiation focusing device, a focusing lens 2 and a slit 3 are provided between a light source 1 and a sample 4 as shown in FIG.
It is known that the sample 4 is arranged by arranging or irradiating the sample 4 with light reflected from the horizontal direction as shown in FIG.

[0003]

However, the above-mentioned known examples have the following drawbacks. a. When simultaneously irradiating and condensing the sample 4 from a plurality (n) of light sources, it is necessary to combine n or more optical components (mirrors, lenses, etc.). Therefore, the support base,
The optical system, including the anti-vibration table, will become large, and it will take time and effort to prepare and adjust before observation. b. It is difficult to measure specular reflections of a plurality of light sources with respect to a sample in zero dimensions because the positions of detectors are considerably limited.

It is an object of the present invention to provide a multiple light source irradiation device which solves the above disadvantages a and b.

[0005]

The constitution of the present invention is as follows.

A multifaceted reflecting mirror having a plurality of reflecting surfaces formed on concentric circles and having a reflection angle of the reflecting surfaces set so as to collect light reflected by these reflecting surfaces at the same point, a light source and a collimator. And a light irradiating device for irradiating the light from the light source to the reflecting surface of the multi-faced reflecting mirror via an optical chopper, a monochromator and a collimator, and a light irradiating device installed in a hole penetrating the center of the multi-faceted reflecting mirror. In order to be able to arbitrarily set the position and angle of the specular reflection light observation device that captures the image from the camera into the amplifier via the optical fiber and displays it on the display,
A multiple light source irradiation device comprising: a support supporting a multi-faceted mirror.

[0007]

The light emitted from the light source toward each reflecting surface is reflected by the reflecting surface and is condensed at the same point (sample). It is possible to collect a plurality of lights at the same time or to switch and collect a single light or an arbitrary combination of a plurality of lights for irradiation and collection. The observation is performed by using the light condensed at this one point.
Observation of specular reflection light is performed with a camera, an amplifier, and a display of a specular reflection observation device installed at the center of each reflection surface.
