Product Description

Quartz/Fused Silica

(UVFS) is ideal for use in applications in the UV range that go beyond the transmission of N-BK7. When compared to N-BK7, UV fused silica is transparent over a wider range of wavelengths (185 nm - 2.1 µm) and also offers a lower index of refraction as well as better homogeneity. It is scratch resistant and has a low coefficient of thermal expansion. UV fused silica exhibits minimal fluorescence when exposed to wavelengths longer than 290 nm. Its index of refraction is 1.458 at 587.6 nm.
