Wafer Glass
This product is made of glass or quartz by cutting and polishing process. Typical sizes are 6 inch, 8 inch and etc. It' s widely applied in integrated fabrication of optical components.
Product application: 1. High refractive index glass wafers can be used in AR video glasses with diffractive optical waveguide technology, and this glass wafer uses high refractive index optical glass materials (Nd=1.8~2.1), which can improve the performance of AR video glasses. Angle of view.
2. Mainly used for bonding with silicon wafers and used as substrates in semiconductor photolithography and packaging processes;
