High transmittance optical glass

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 information

Compared 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.

Technical information

The difference between the refractive index nd and Abbe number of each batch of products ud from the standard value is generally within the following tolerance range：

折射率nd：±30×10-5；

阿贝数υd：±0.5%。

If there is any special requirement, supply can be made based on the following standards:

板料折射率nd：±2×10-5~±5×10-5；

阿贝数υd：±0.3%。

Major application

They are mainly used for high definition imaging equipment such as intelligent driving cameras, laser radar, astronomical telescopes and digital projectors, etc.
