Calcium Fluoride
• Greater than 90% Transmission from 250nm-700 nm
• Low Index of Refraction
Calcium Fluoride optics are typically used in spectroscopic windows and lenses due to its high transmission from 250nm to 7µm. Calcium Fluoride is also commonly found in cryogenically cooled thermal imaging systems. Its low absorption and high damage threshold makes it a popular choice for excimer laser optics. Calcium Fluoride's low refractive index allows it to be used without an antireflective coating. The Knoop hardness of Calcium Fluoride is 158.3.

Fused Silica
UV Grade lenses are precision manufactured using research-grade synthetic fused silica. In addition to providing excellent transmission characteristics and higher operating temperatures, synthetic fused silica lenses also exhibit an exceptional inclusion specification and chemical purity. These lenses make a superior choice for many laser and imaging applications, particularly those involving ultraviolet wavelengths. A broadband anti-reflection coating is avaliable for optimized throughput in the ultraviolet spectrum.
