Study On Lightweight Mirror Manufacturing Technology

Being lightweight of mirror is a very important subject in high accuracy sighting/image stabilizing technique. The manufacturing technology that fusion glass and metal together to manufacture a new type mirror using the characteristics of the two materials is an important way to solve the subject.On the foundation of consulting many literatures overseas and home, starting from material choosing, the stress situation before and after fusion sealing of glass and metal in processing, the method to eliminate the stress, the fusion sealing of glass and metal, the treatment after fusion sealing, a lot of experiments were did and the sealing material of glass and metal, fusion sealing temperature and control process etc. technical factors are determined. Meanwhile, a solution against blowout of glass in after-processing is raised. Finally, the selected optimized technical parameters and improved technical method are experimented separately and a manufacturing technical technique of lightweight mirror is formed.
