Technical Field

[0001] The invention relates to the technical field of optical element inspection, in particular to a fast replacement and positioning device for optical elements. Background Art

[0002] Optical films are widely used on the surface of various optical glasses to obtain certain effects, such as anti-reflection films, reflective films, filter films, etc. These gain-type effects have an important influence on the performance of optical glass. Accordingly, the quality of optical films becomes an important part of the quality of optical glass. Therefore, it is necessary to test the formed optical films.

[0003] Due to the different applications of optical glass, its shape and size vary greatly, and the detection equipment needs to have good adaptability to the size changes of optical glass; on the other hand, when detecting optical films, there are strict requirements on the distance between the optical film and the lens. A slight deviation will deviate from the focus and cause the detection to fail. Therefore, it is necessary to design a fixture that can achieve fast clamping, which has good adaptability to optical components of different sizes and shapes, and can quickly replace component samples and achieve accurate positioning of the film surface.
