A spherical lens is an optical device which transmit and refract light,converging or deverging the beam.A simple spherical lens consists of a single optical element.A compond spherical lens is an array of simple lenses(elements) with a common axis;the use of multiple elements allows more optical aberrations to be corrected than is possible with a single element. Specification of spherical lenses we could meet normally: Material:BK7 or other materials Focal length:+/-1% Center thickness tolerance:+/-0.01mm Centration:1 arc minutes Surface Figure:lambda/10 at 633nm on plano side Surface quality:10-5 Clear Apenture>98% Chamfer Protective:0.25mm at 45 degree typical Coating:optional Beside,plano concave spherical lens,bi-concave spherical lens,bi-convex spherical lens,meniscus spherical lens are also availble here,VY Optics would also like to design spherical lens as per your requirement.
