• Fabricated from UV Grade Fused Silica
• UV AR Coating for the 290 - 370 nm Range
• Ø6 mm Plano-Convex Spherical Singlet Lenses

The LA4917-UV UV Grade Fused Silica Plano-Convex comes with a UV antireflection coating for the 290 nm - 370 nm range. This UV antireflection coating is particularly desirable for applications with multiple optical elements. Fused Silica Plano-Convex lens 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.

Plano-convex lenses focus a collimated beam to the back focus and collimate light from a point source. If the desired absolute magnification is either less than 0.2 or greater than 5.0, it is usually preferable to use a plano-convex lens (rather than a bi-convex lens which also causes collimated incident light to converge). Also, when image quality is not critical, plano-convex lenses can also be used as an economical substitute for achromatic doublets.
