Problems solved by technology
However, existing glass detectors may make mistakes in judging the bright field or dark field after the brightness of the light source is changed or people who are not familiar with the detector, thus causing errors in the judgment of the type of glass to be detected. The glass identifier is only suitable for identification between two glasses

Abstract
The invention relates to a glass identification element, a glass identification device and a glass identification method. The glass identification element comprises at least two prisms, the first prism and the second prism are respectively provided with a first detection surface and a second detection surface which are parallel to the surface of first glass to be identified and are respectively made of materials with a first refractive index and a second refractive index, the first detection surface and the second detection surface are coplanar and are used for mutually comparing view fields formed when light rays are incident to the first detection surface and the second detection surface when being placed on the first glass surface to be identified, and the light rays are totally reflected when being incident to the first detection surface and are not totally reflected when being incident to the second detection surface; or when the light is incident to the first detection surface and the second detection surface, total reflection does not occur or total reflection occurs. According to the invention, the glass to be detected can be more accurately judged, and the glass identifier element, the glass identification device and the glass identification method which are easier to operate and wider in application are provided.
Description
technical field [0001] The present invention relates to a glass identification element, more particularly, to a glass identification element for quickly judging the type of glass. The invention also relates to a glass identifier comprising the same. Background technique [0002] In existing glass identification devices, a single prism is usually used as a glass identification element, and a single prism is placed on the surface of the glass to be tested to observe the brightness change of the field of view on the interface between the single prism and the glass to be tested, and then according to the refractive index of the prism , to determine the approximate range of the refractive index of the glass to be tested, thereby determining the type of glass to be tested. However, the existing glass detectors may make mistakes in judging the bright field or dark field after the brightness of the light source is changed or people who are not familiar with the detector, thus causi...
