Calcium Fluoride CaF2 Crystal Windows Product Attributes
Calcium Fluoride (CaF2) crystal has excellent transmission in the UV, they are often used to make windows from below 150 nm and extending throughout the visible range. The material of CaF2 IR Windows are relatively soft and somewhat hygroscopic, Polished surfaces are stable and will last several years under normal conditions,so polishing and coating during processing are more critical. Coupletech provides CaF2 IR crystal shows good optical and thermo-mechanical properties, can be used for Optical Windows, Optical Mirrors , Optical Lenses, Optical prisms within a wide range from 130nm to 9μm. CaF2 has optical properties of isotropy, low absorption and low refractive index, which made Calcium Fluoride (CaF2) gain the unique advantages in the application of high power lasers. CaF2 IR viewport Windows for Infrared Thermography at 8μm to 10μm; Various optics for IR & VUV application. Using Coupletech Calcium Fluoride CaF2 crystal materials; Good quality CaF2 crystal blank materials; OEM service for good quality CaF2 crystals. Coupletech also provides other Optical Elements such as : Optical Filters and Beamsplitter.
