Embodiment Construction

[0017] The invention is based on the effective control of chemical corrosion, realizes the temperature distribution of different ring zones of optical workpieces through radiation, and removes quantitative materials from optical elements. In view of the impact of chemical corrosion on the quality of optical surfaces, mechanical methods are used to complete the final polishing of optical surfaces forming.

[0018] The present invention uses microwave radiation or projection to achieve a definite temperature distribution, and combines chemical corrosion polishing and mechanical polishing. The former mainly realizes the removal of workpiece material, and the latter is mainly for obtaining a smooth surface; it is suitable for rapid grinding of large-diameter aspheric optical elements and polished.

[0019] The grinding and polishing device for accelerated corrosion by radiation temperature field includes temperature field generating equipment 1, controller 2, computer 3, transpare...

Abstract

The invention provides a grinding and polishing device for accelerated corrosion of a radiation temperature field, and mainly solves the problem that the conventional optical elements, in particular the non-spherical optical elements are higher in processing cost and lower in processing efficiency. The grinding and polishing device comprises a bearing mechanism for bearing processed elements as well as a corrosion liquid storage tank, wherein all the processed elements are soaked in the corrosion liquid storage tank by the bearing mechanism; a transparent grinding tool is configured and is in mechanical contact with the processed elements; temperature field generation equipment is connected with a control mechanism; and both the bearing mechanism and the corrosion liquid storage tank are fixedly arranged on a rotary shaft. The grinding and polishing device can be used for quickly polishing the non-spherical optical elements, and is low in cost and suitable for grinding and polishing the large-diameter optical elements.

Description

technical field [0001] The invention relates to an optical element processing device, in particular to a lapping and polishing device suitable for rapid grinding and polishing of large-diameter and aspheric optical elements in the radiation temperature field accelerated corrosion. Background technique [0002] Aspherical optical components have many advantages such as correcting various aberrations, improving imaging quality, simplifying optical systems and expanding the field of view, etc., and have been widely used in many optoelectronic products in military and civilian fields. However, the processing of aspheric surfaces still has the problems of expensive equipment, low precision, and low efficiency, which seriously restricts the development of related industries and scientific research projects. [0003] At present, optical processing includes advanced technologies such as CCOS, magnetorheology, and ion beam. At present, small grinding head technology has become the ma...
