CaF2 Window,CaF2 Spherical Lens, CaF2 Prisms.
Low solubility and wide transmission range makes it useful for many applications, including: mirror substrate for UV laser systems; substrate for manufacturing windows, lenses for UV, IR applications.
Calcium Fluoride (CaF2) is commonly used for optics looking at the IR and UV spectrums and has a very low change in refractive index with wavelength. It shares similar optical properties with Barium Fluoride although it has a transmission that is 2.5µm less into the infra-red. Calcium Fluoride is however cheaper than Barium Fluoride as the optical grade occurs naturally as opposed to BaF2 being man made.
CaF2 (Calcium Fluoride) windows are often used in infrared spectroscopy and imaging applications due to their exceptional transmission in the range of 0.2 to 10 microns. They are also highly resistant to thermal and mechanical shock and have a low index of refraction, making them suitable for applications that require a high degree of clarity and resolution. Some common applications of CaF2 windows include gas and liquid cell windows, specialty lenses, and optical components for medical and scientific research. Additionally, CaF2 windows can be used in harsh environments where other materials may deteriorate, making them highly versatile in a range of industries.
