Calcium Fluoride Crystal High performance Caf2 optica viewport windows

Calcium fluoride shows good optical and thermo-mechanical properties. It is widely used as optical windows, lenses and prisms in 0.13μm~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.

Calcium Fluoride crystal shows good optical and thermo-mechanical properties, can be used for optical windows, lenses, prisms within a wide range from 130nm to 9μm. It has optical properties of isotropy, low absorption and low refractive index, which made CaF2 gain the unique advantages in the application of high power lasers.

Scitlion is able to offer
CaF2 IR viewport Windows for Infrared Thermography at 8μm to 10μm
Various optics for IR & VUV application, using our CaF2 crystal materials
