Spherical biconvex lenses of fused silica are mostly used for UV monochromatic lights. Fused silica has almost same performance of transmittance with BK7 in visual and near IR, but has higher performance than BK7 in UV.
The lenses are polished carefully by selecting materials (striae, bubbles, inclusions, and homogeneity) and paying attention to dispersion (digs, scratches, and glosses) to prevent troubles with coherent light
Uncoated and coated with broadband multilayer AR coatings for visible are available.
