Frequently Asked Questions — Calcium Fluoride (CaF₂)
What is Calcium Fluoride (CaF₂) used for?
Calcium Fluoride (CaF₂) is a widely used optical crystal with excellent transmission from deep ultraviolet to infrared. It is commonly used in spectroscopy, laser optics, semiconductor lithography, and aerospace optical systems.
What wavelength range does CaF₂ transmit?
CaF₂ provides high optical transmission from approximately 150 nm to 8 µm, covering deep UV, visible, and infrared regions.
How does CaF₂ compare to MgF₂?
Compared with MgF₂, CaF₂ offers a slightly higher refractive index and broader infrared transmission, while maintaining low birefringence and high laser damage resistance. CaF₂ is often preferred for high-power laser windows and broadband optical components.
Is CaF₂ suitable for high-power laser applications?
Yes. CaF₂ has a high laser damage threshold and excellent thermal and radiation resistance, making it suitable for excimer lasers, CO₂ lasers, and other high-power laser systems.
Is CaF₂ resistant to moisture and harsh environments?
CaF₂ shows good resistance to moisture, thermal shock, and radiation exposure. It is widely used in space, aerospace, and long-term industrial optical environments.
What forms and components are available?
CaF₂ crystals can be supplied as optical windows, lenses, prisms, substrates, and fully custom-shaped components according to your optical design requirements.
Do you provide custom sizes and optical polishing?
Yes. We offer custom dimensions, thicknesses, edge profiles, and optical-grade polishing to support research, prototyping, and OEM production.
Are CaF₂ crystals suitable for research and production use?
