Knight Optical’s UV Fused Silica Lenses for Solid-State Lasers
23 Sep 2021
Knight Optical can offer custom and stock UV Fused Silica Lenses for Solid State Laser applications
We supply a range of UV grade Fused Silica lens options for a range of applications – all individually QA checked and metrology tested for quality to ensure parts meet customer specification. What’s more, our UV Fused Silica Lenses are supplied in a range of sizes and shapes with custom coatings tailored to meet your individual applications.
UV Fused Silica is a prime choice for lenses in use with Solid-State Lasers due to its consistently high transmission in the ultraviolet (UV), visible (VIS) and near-infrared (NIR) regions. This means that it can be used with a range of different laser types, such as Titanium-Doped Sapphire (tuneable to 660-1080nm) or Alexandrite (tuneable to 700-820nm) with very little change in performance.
UV Fused Silica is comparable to N-BK7 (or equivalent) in its performance, having a very 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 slightly higher.
