UV Fused Silica Lenses
Worked from 190nm ~2100nm, our lenses will not fluoresce under UV light and is
resistant to radiation. The material can be Chinese JGS1, Corning 7980. Other
manufacturers' material are available.
Our diameters are from 1.50 mm to 250 mm. They can be uncoated or multi-layer
AR coated.

CaF2 Lenses ( Calcium Fluoride Lenses)
Greater than 90% Transmission from 350nm-7um
Low Index of Refraction
Calcium Fluoride is often used in spectroscopic
windows and lenses due to its high transmission from
350nm to 7pm. 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.
