| can customize as your size and wavelength | |||
we support the customization as your sample, at present, we have done the mirrors. It is widely used in Laser cutting and welding machines.
laser protection lens main role is to block debris splash, to prevent spatter injury lens. Both sides plated high damage threshold (> 15J/cm2)antireflection coating to reduce reflections.

K9 or China quartz(JGS2) is mainly use for 1-300W
China quartz(JGS1) is mainly use for up to 1000W
Import quartz is use for up to 5000W
Please note that it means the using power, the K9 and China quartz also can be applied to 2000W fiber laser cutting machine and it won't hurt your laser machine, you can buy some to test. The Import quartz is the most widely used, its life is longer and cutting efficiency is better.
The laser equipments wavelength: 1064-1080nm
Technical parameter data:
Plated 1064nm AR film K9 T> 99.65 (quartz T> 99.9%).
