Product Description

Calcium fluoride shows good optical and thermo-mechanical properties. It is widely used as optical windows, lenses and prisms in 0.*3μm~9.0μm. For its optical isotropy, low absorption and low refractive index. CaF2 has found unique advantages in high power laser and UV laser optics.
