Description
- Very hard and rugged
- Resistant to mechanical and thermal shock
- The only one optical material combining a wide spectral transmission band with birefringence phenomenon
Magnesium fluoride (MgF₂) is a proven material for high energy lasers, and particularly for lasers operating in the UV range. Generally all optical elements are manufactured with the working surface perpendicular to the c-axis MgF₂ crystal.
