Light reflecting glass mirror and manufacturing method thereof

Abstract

The invention discloses a light reflecting glass mirror and a manufacturing method thereof, wherein the manufacturing method comprises the following steps: S1, providing a plurality of semifinished panels and a plurality of semifinished rib plates; S2, using two semifinished panels respectively as a bottom plate and a top plate of the light reflecting glass mirror, using a plurality of semifinished rib plates as rib plates of the light reflecting glass mirror, and processing the bonding surfaces of the rib plates; S3, coating glass powder on the bonding surfaces in a clearance type manner, premounting the rib plates between the bottom plate and the top plate according to the distribution of the bonding surfaces, and removing redundant glass powder; S4, sending the bottom plate, the top plate and the rib plates, which are premounted, in a heating furnace, heating the heating furnace to a temperature which is 9-10 degree higher than the fusion point of the glass powder, keeping the temperature for at least 10 minutes, and after heating, cooling the heating furnace to drop the temperature so as to obtain the light reflecting glass mirror. The manufacturing method disclosed by the invention is safer, the manufactured light mirror has the characteristics that the self-weight deformation of the reflecting mirror, the thermal resistance in the thickness direction, and the deformation caused by temperature gradient are reduced, and the thermal radiation area of the reflecting mirror is enlarged.

Description

technical field [0001] The invention relates to a manufacturing method of an optical device, in particular to a glass lightweight reflector and a manufacturing method thereof. Background technique [0002] The world's first artificial earth satellite weighs 81.5kg. Since then, the development trend of satellites is to increase the size and quality of satellites in order to obtain expected economic and military benefits. In order to improve the ground resolution of remote sensing instruments, catadioptric or all-trans optical systems with long focal length and large relative aperture are usually used, so the aperture and quality of optical parts are getting larger and larger. [0003] As the size and mass of satellites increase, the launch expense, complexity and cost increase accordingly. Therefore, people begin to pay attention to the research of small and light remote sensing instruments. Because the main optical part of the catadioptric or all-reflective optical system i...

Problems solved by technology

[0004] However, the existing methods for manufacturing glass light-weight reflectors have a low success rate, and it is easy to cause problems such as bursting of the manufactured reflectors. The risk is relatively large, and phenomena such as bursting are prone to occur during processing.
