Please send us your specifications, we will quote it for you within 24 hours.
Fused Silica is used for lenses in the transmission range 0.18-3.5µm. Fused Silica refractive index varies from 1.55 to 1.40 through the transmission range. Fused Silica lenses resistant to scratching and thermal shock, and suitable for large number of laser and optical applications. AR Coatings can be applied on Fused Silica lenses to improve transmission on your laser line or broadband spectrum range.
