Product overview

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
Good quality CaF2 crystal blank materials
OEM service for good quality CaF2 crystals
Orientation:<100>、<110>、 <111>
