DUV grade MgF2 material has a transmission more than 65% at 121.6nm. Of course this grade material can be used for excimer & Nd:YAG laser optics. The quality of a DUV window can be extremely critical; it should be of high purity and polish in order not to affect the optical system.
Key features:
- UV grade
- High precision
