Calcium Fluoride (CaF₂)

Calcium Fluoride is a widely used material in the optical industry due to its excellent transmission properties across a broad spectrum, from ultraviolet (UV) to infrared (IR). Its low refractive index minimizes reflection losses, making it ideal for high-performance optical systems. The material’s high laser damage threshold and thermal stability make it particularly well-suited for use in excimer lasers, thermal imaging, and other IR applications where durability and clarity are crucial. Its ability to withstand high temperatures and offer low dispersion makes it a preferred choice in precision optical components.
