Calcium Flouride -CaF2
Calcium Fluoride (CaF₂) is a high-performance optical material known for its excellent transmission from the deep UV (~180 nm) to the mid-infrared (~8 µm). With low absorption, minimal fluorescence, and a high laser damage threshold, CaF₂ is ideal for laser optics, spectroscopy, and cryogenic applications. Its low refractive index (~1.43 @ 1 µm) also reduces the need for anti-reflective coatings in many systems.
At Global Optics UK, we offer precision-fabricated Calcium Fluoride windows, lenses, and prisms, with full customization options for size, coating, and surface quality — ready for demanding optical applications

FAQ
FAQ
Q: What is Calcium Fluoride used for?
A: CaF₂ is widely used in infrared and ultraviolet optical systems, including lenses, windows, and prisms for spectroscopy, thermal imaging, laser systems, and astronomy.
Q: What is the transmission range of CaF₂?
A: Calcium Fluoride offers excellent transmission from approximately 150 nm (UV) to over 9 µm (IR), covering a wide spectral range for various optical applications.
Q: Is CaF₂ mechanically durable?
A: Yes, CaF₂ is relatively hard (Knoop ~158) and chemically stable, but it is brittle and prone to chipping under mechanical stress. It should be handled with care during fabrication and mounting.
Q: Is Calcium Fluoride hygroscopic?
A: No, CaF₂ is non-hygroscopic and resistant to moisture, making it suitable for use in humid or outdoor environments.
