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.
Opticreate provides CaF2 viewport Windows for Infrared thermography at 8μm to 10μm and also manufactures high precision CaF2 lens. Also do AR coating according to customer’s requirements.
