Abstract

The present invention is retouching method of small planar optical element. The retouching method features the parameters of: retouching mold diameter of 150 % to 300 % of the optical element, pressure of the retouching mold on the optical element of 3-10 kg, rotation speed of the retouching mold in 45-80 rpm and asphalt hardness of 61-63 deg. The present invention has stable product quality and high production efficiency.

Description

(1) Technical field [0001] The invention relates to a large mold manual repair method for small plane optical parts. (two), background technology [0002] Manual repair is an important process in the processing of planar optical parts. For high-precision optical parts, that is, parts with relatively high technical requirements on smoothness, aperture, parallelism, angle, star point, etc., manual repair is essential of. In the manual repair process, choosing the diameter of the manual repair mold is a key part. The traditional method is: the diameter of the manual repair mold is 15%-25% larger than the diameter of the part. The polishing asphalt used has a hardness of 60° and light pressure. Its disadvantages are: unstable processing quality and low efficiency. (3) Contents of the invention: [0003] In order to overcome the shortcomings of the prior art, the present invention provides a large mold manual repair method for small plane optical parts, which not only has s...
