Description

technical field

[0001] The invention relates to an optical element processing system and method, in particular to a large-diameter optical glass grinding and polishing system and method. Background technique

[0002] Large-aperture optical components are an important part of many large-scale optical systems, and their effective aperture and surface accuracy fundamentally determine the performance of the optical system. At present, there are generally two methods of processing and manufacturing in this field: one is to adopt the classical method of polishing, and the manual grinding is repeated for many times. This requires professionals to have rich processing experience, and this method has disadvantages such as low efficiency, many human factors, long processing cycle and high labor intensity; the second is CCOS (Computer Controlled Optical Surface Shaping) equipment processing, this method has good The comprehensive benefits of processing, high equipment precision, and g...
