UV-Grade Fused Silica Plano-Concave lenses have a UV antireflection coating for the 245 - 400 nm range deposited on both surfaces. 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. In addition, UV fused silica has better homogeneity and a lower coefficient of thermal expansion than N-BK7.The additional UV antireflection coating on these plano-concave lenses is particularly desirable for applications with multiple optical elements.

Plano-concave lenses have negative focal lengths, making them useful for a wide range of applications. They are commonly used to diverge a collimated incident beam; in such cases the collimated light source should be incident on the curved surface to minimize spherical aberrations.
