Main Characteristics

1).Excellent UV Transmittance
2).High laser durability
3).Low stress birefringence
4).High refractive index homogeneity
5). Calcium fluoride features a very low spectral dispersion, a low non-linear refractive index and is available in sizes up to 440 mm diameter. These advantages make it a superior optical material for vacuum windows for spatial filters, target and compressor chambers.
