Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-2, the present invention provides a technical solution: a lens with concave lens function and convex lens appearance comprises a lens 1 and a prism 2 which are formed by deflection surfaces for inward deflection of the lens; the lens 1 and the prism 2 are formed integrally or spliced together, when the center distance between adjacent micro prisms on the prism 2 is infinitely close to 0, the lens is infinitely close to a concave lens in function and is infinitely close to a convex lens in appearance.

The lens 1 is any one of a single convex lens, a double convex lens, a convex-concave lens, a single concave lens, a double concave lens and a concave-convex lens.

Wherein the prism 2 is arranged on the curved surface of the lens 1.

Wherein, a reflective film is plated between the prism (2) and the lens 1, and after film plating, not only refraction but also reflection exist in the light path of the prism, so the imaging effect is better.

The lens 1 and the prism 2 are made of any one or a combination of several of transparent materials, semitransparent materials or colored transparent materials.

The lens 1 and the prism 2 are made of any one or a combination of several of glass, plastic and solid state of transparent liquid.

Wherein the interval of the prisms 2 is 1 nanometer to 0.1 light year.

The cross section of the prism 2 is formed by intersecting a concentric elliptic curve with the surface of the lens 1 and a deflection surface.

Wherein, the prism 2 is an N prism, and N is more than or equal to 3.

The cross section of the prism 2 is any one or combination of more of an isosceles acute triangle, an isosceles obtuse triangle, a scalene triangle, an equilateral triangle or a polygon.

The working principle is as follows: the working principle of the convex lens is the refraction principle of light, the refraction of the light only occurs when the light obliquely enters another transparent medium from one transparent medium, and the movement in the same medium does not change, so the light condensation principle of the convex lens only occurs on a transparent curved surface, and the design idea of the scheme is to change the curved surface of the lens, so that the curvature of the original curved surface is changed, and the refraction direction of a light path is changed;

the principle of the reflection film plating is as follows: the prism sets up on the curved surface of lens, shine on the prism when light, the prism has the contained angle with light, consequently, after light jets into the prism, take place the refraction behind the light, and behind the coating film, after light jets into the prism, the prism is still refracted back to light, the light irradiation that is more than is back on the reflective membrane of prism, can be reflected by the reflective membrane of prism, light after the reflective membrane reflection is unanimous with the light path of prism refraction, consequently, do not influence the formation of image effect, and no matter be light after the prism refraction or the light after the reflective membrane reflection all moves in same kind of medium, consequently, the light path inside lens is linear motion, thereby the convex lens who has concave lens function has been reached.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
