CaF2 (Calcium Fluoride) Pellets Granules Evaporation Materials
- Broad Transparency Range: CaF₂ has excellent transmission from the UV (below 200 nm) to the IR (~10 µm) range, which makes it ideal for a wide variety of optical applications.
- Low Refractive Index: The material has a relatively low refractive index (~1.43), which minimizes Fresnel reflection losses and is useful in anti-reflective coatings.
- High Thermal Stability: CaF₂ can withstand high temperatures during evaporation, ensuring the stability of the material during thin-film deposition processes.
- Chemical Resistance: Calcium fluoride is chemically inert, offering durability and resistance to environmental degradation.
- Low Absorption: Its low absorption makes it suitable for high-power laser applications, especially in the UV region.

CaF₂ (Calcium Fluoride) pellets are commonly used as an evaporation material in physical vapor deposition (PVD) processes, particularly for optical thin-film coatings. Calcium fluoride is well-known for its wide transparency range, from ultraviolet (UV) to infrared (IR), making it ideal for creating coatings on lenses and other optical components used in lasers, telescopes, and other precision optical instruments.
Key Applications:
- Optical Coatings: CaF₂ is used in anti-reflective (AR) coatings and protective coatings for UV, visible, and IR optical components such as lenses, windows, and prisms.
- UV and IR Optics: Widely used in UV and IR optics due to its high transmission over a broad wavelength range (from 0.13 μm to 10 μm), making it ideal for UV excimer laser systems, IR imaging systems, and spectroscopy.
- Telecommunication: CaF₂ thin films are used in optical fibers and other components in telecommunication systems.
- Lithography: It is also applied in optical lithography systems due to its exceptional transparency in the deep UV region.
