K9 Optical Window‌

K9 window sheet is a type of glass grade produced by Chengdu Guangming. Its refractive index is 1.51630 and its dispersion coefficient
It is 0.00806 and the Abbe number is 64.06. Similarly, customers will require coating to achieve high transmittance and low refraction, allowing
Let as much light as possible pass through.
The characteristics of K9 glass: high transmittance in the visible wavelength range and extreme resistance to ultraviolet radiation
Stability (test procedures in accordance with internal regulations). Easy to process, with excellent temperature resistance and chemical retention. We
The available glass forms include cut pieces, strips, droplet shapes, rods and glass sheets, etc. We needle
Provide corresponding solutions specifically for the handling and processing technologies of customers. We implement precise process control
Strict quality control and management ensure the high quality of the products.

400~1100nm@T>92%
The transmittance can reach 98% after double-sided AR coating
