Plano-Convex Spherical Lenses are available in both Laser Quality and Analytical Quality polish designated as LQ ( Laser Quality) and AQ (Analytical Quality).  Plano-Convex Spherical Lenses are available in UV Grade Fused Silica (FS) & BK7 Glass materials*.  Plano-Convex Spherical Lenses have one flat (plano) surface and one spherical surface curved outward (convex) to converge the transmitted rays from an object, thus forming a real or virtual image of that object.  A Plano-Convex Spherical Lens is used as a simple imaging lens to focus, collect and collimate light.  These lenses have positive Effective Focal Lengths. * Also see our VUV grade CaF2 & MgF2 Lenses for Vacuum UV (VUV) applications.   For more information about Spherical Lenses, refer to our Optics Tutorial page.                                  SPECIFICATIONS Material : BK7 Glass & UV Grade Fused Silica (FS) Effective Focal Length Tol.: LQ=± 0.5% / AQ=± 3%      Diameter (Dia = Ø) Tolerance: ± 0.25mm Thickness Tolerance: ± 0.25mm   Surface Figure: LQ = l/10 @ 633 nm nominal                              AQ = ~l/2 @ 633 nm nominal                  Surface Finish:  LQ = 10-5 both surfaces                              AQ = < 60-40 both surfaces Clear aperture: central 85% Centration: < 3 arc minutes  Chamfer: ~ 0.30mm @45 deg.
