Calcium Fluoride - CaF2
Calcium fluoride (CaF2) is a crystalline compound with a cubic crystal structure. This popular optical material can be used across a wide range of ultraviolet (UV), visible, or infrared (IR) applications due to its unique optical properties.
Here at Global Optics, we manufacture calcium fluoride optical components for various industries.
Why is calcium fluoride used in optics?
Given that calcium fluoride's optical properties are so adaptable across a broad spectrum, many industries can benefit from CaF2 components.
Some of the key optical properties of calcium fluoride include:
High transmittance: Calcium fluoride has a high transmittance across a wide range of wavelengths, making it a useful material for applications in ultraviolet, visible, and infrared regions of the electromagnetic spectrum.

Low refractive index: Calcium fluoride has a relatively low refractive index of 1.43 or homogeneity, making it useful for optical components such as lenses and prisms.
Low dispersion: Calcium fluoride has a low dispersion, meaning that it can transmit light of different wavelengths without significant colour separation or distortion.
Low absorption: Calcium fluoride has a low absorption coefficient, and therefore can transmit light with minimal loss. This property makes it useful for optical components in high-power laser systems.
High thermal stability: Calcium fluoride has a high thermal stability, allowing it to be used in high-temperature applications without significant degradation of its optical properties.
High resistance to radiation damage: Calcium fluoride is highly resistant to radiation damage, making it useful in applications that involve radiation exposure.
High damage threshold and mechanical strength: The mechanical properties of calcium fluoride include an impressive ultimate tensile strength (UTS) of 34.1 to 157 MPa. CaF2 also offers excellent water, chemical, and heat resistance.
