high transmittance optical glass refers to the optical glass whose transmittance in the blue-violet and visible light range is increased through slight adjustment of fomula and process improvement. the high transmittance glass can be used for improving the image quality of optical system with long optical path.
product informationcompared withordinary optical glass, high transmittance and ultra-high transmittance optical glass only improves transmittance, while other properties remain unchanged on the whole. currently, the company has more than 10 types of high transmittance optical glass.
