Product Application

Calcium fluoride crystals (CaF ₂) have optical properties such as high refractive index, high transmittance, and low dispersion, making them widely used in multiple fields. Its main uses include:

Optical applications: Calcium fluoride crystals are used to manufacture optical components such as lenses, prisms, and windows, especially in infrared optical systems. They are also used to make large-sized lenses, such as those used in laser lithography, and in the field of high-energy detection.
Ceramic and Glass Industry: As an important raw material for ceramic and glass manufacturing, calcium fluoride can improve the transparency and heat resistance of ceramics, reduce the melting point of glass, and improve fluidity.
In the fields of medicine and biology, calcium fluoride crystals have certain biocompatibility and can be used as drug carriers, tissue engineering scaffold materials, bone defect filling, and tooth restoration.
Laser: Due to its excellent transparency and radiation resistance, calcium fluoride crystals are used to manufacture pulse lasers and Q-switches, suitable for strong radiation environments.
X-ray detector: Calcium fluoride crystals can strongly absorb X-rays and convert them into charges, used in fields such as medical imaging and mineral detection.
Fiber optic communication: In fiber optic communication, calcium fluoride crystals can be used as optical components such as couplers and wavelength splitters, and their excellent transmittance and thermal stability can be used to improve the performance of photoconductive devices.
