UV Fused Silica Windows, Uncoated, High Precision Windows
Overview:
UV-grade fused silica Wondows are well-suited for applications that benefit from increased transmission deeper into the UV than N-BK7. UV fused silica window also offers a lower index of refraction for a given wavelength, better homogeneity, and a lower coefficient of thermal expansion than N-BK7.
