Knight Optical’s UV Fused Silica Lenses for Solid-State Lasers

19th Sep 2018

Our UV Fused Silica Lenses are the component of choice for solid-state laser applications due to their consistently high transmission in the ultraviolet (UV), visible and near-infrared (NIR) spectrums. Their versatility means they can be used for a range of laser types – for example, titanium-doped sapphire (tuneable to 660-1080nm) or alexandrite (tuneable to 700-820nm) – with very little change in performance.

Similar to N-BK7 (or equivalent) in performance, UV Fused Silica has a remarkably similar average transmission over the visible range, up to approximately 2000nm, and a slightly lower refractive index.  The Abbe constants of UV Fused Silica are also very similar to that of N-BK7 (or equivalent), although somewhat higher.
