| Material Properties |
|
Magnesium Fluoride (MgF2 window) has excellent transmission in the UV. This material can reach transmission greater than 50% at 121.6nm and it can be used for excimer & Nd:YAG laser optics. MgF2 is relatively soft and somewhat hygroscopic so polishing, coating and handling are more critical than for Fused Silica windows. The quality of a UV window can be extremely critical, it should be of high purity and polish in order not to affect the optical system.
