UV FS Lenses for Solid State Lasers

Photonics Buyers' GuideLenses for Solid State LasersKnight Optical can offer UV Fused Silica Lenses for Solid State Laser applications. UV FS is a prime choice for lenses in use with Solid State Lasers due to its consistently high transmission in the UV/VIS/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 FS is comparable to N-BK7 or other similar optical glasses in its performance, having a very similar average transmission over the VIS range up to approximately 2000nm and a slightly lower refractive index. The Abbe constants of UV FS are also very similar to that of N-BK7, although slightly higher.

Typical specs: Material: UV Grade Fused Silica Operating Wavelength 587nm    •   Diameter Tolerance: +0 / -0.10mm    •   Centering Tolerance <5 arc min    •   Focal Length Tolerance: ± 0.2mm (<10mm) ±2.0% (10mm – 1000mm)    •   Centre Thickness Tolerance ±0.2mm Surface Figure 3/ 3 (1)    •   Surface Quality: <40-20    •   Scratch/Dig Coating: Optional
