  • Much like surface flatness for flat optics, spherical surface power is a measure of the deviation between the surface of the curved optic and a calibrated reference gauge. This specification is also commonly referred to as surface fit.

  • Material: UV-Grade Fused Silica
  • AR V-Coating: <0.25% Reflectance at 1064 nm
  • Ideal for Use with Nd:YAG Lasers
  • Focal Lengths Available from 20 mm to 1000 mm

Thorlabs' UV-Grade Fused Silica Plano-Convex Lenses are available here with an AR V-coating on both surfaces that has a reflectance of less than 0.25% at 1064 nm. With diameters of 1/2" or 1", they are compatible with a variety of Thorlabs' fixed and translating lens mounts (see the Mounting Options tab for details).

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 low <0.25% reflectance per surface at 1064 nm makes these V-coated lenses ideal for use with Nd:YAG lasers, as well as in complex systems requiring many optical elements. These lenses offer an improved surface quality and damage threshold compared to our 532/1064 nm V-Coated Plano-Convex Lenses; see the table to the right and the Damage Threshold  tab for more details.
