Product Drawing

Choose a UV Fused Silica Right-Angle Prism if your application would benefit from higher transmission in the UV or a lower coefficient of thermal expansion. UV-grade fused silica offers high transmission in the deep UV and exhibits virtually no laser-induced fluorescence (as measured at 193 nm), making it an ideal choice for applications from the UV to the near IR. For a given wavelength, UV fused silica also has a lower index of refraction than N-BK7.
