Description

Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to a special clamp used for non-core multi-point detection lenses of interferometers. Background Art

[0002] Interferometers can be divided into two categories: single-path interferometers and multi-path interferometers. The difference lies in whether the interfering waves propagate through the same path. The fixed triangular claw of the interferometer is a built-in device of the instrument. The triangular claw is used to clamp and fix the circular lens for detection.

[0003] When common optical interferometers detect optical lenses, they need to use triangular claws to fix the lenses before testing can be performed. However, the stability of the lenses with this traditional fixing method is average. It is fine when fixing round lenses, but if the lenses are of other shapes, the stability will be greatly reduced. In addition, the traditional fixing method has a large degree of freedom of the triangular claws, which can easily cause the lens to deflect during fixation, and the lens is no longer in a vertical state, resulting in detection failure. When the lens requires multi-point detection, the traditional fixing method requires frequent upper and lower fixation, which is extremely cumbersome. The triangular claws are built-in devices of the interferometer and have their own extreme fixing range. When the lens is too large, it is difficult for the triangular claws to fix the lens, which seriously affects the lens detection.

[0004] Based on the above technical problems, technicians in this field urgently need to develop a special fixture for interferometer non-core multi-point detection lenses that has a simple structure, can clamp and fix lenses of different shapes and sizes, and can effectively prevent the angle deflection of the lenses.
