Description

Technical Field

[0002] In the field of optics, when testing optical indicators, the distance between light spots is a very important indicator. Different products have different requirements for the distance of light spots. Especially for invisible light bands, fluorescent materials are often required. For light spots with smaller distances and invisible light, autocollimators can be used for testing without fluorescent materials. However, for light spots at a longer distance, autocollimators are not very suitable. In addition, due to the long distance between light spots, if fluorescent materials are used to measure the relative distance of the entire surface during testing, the cost is high and it is not easy to implement.
