Microlenses arrays are a vital part of today's optical systems. From telecommunications to machine vision, microlenses are impacting the way we live. Shanghai Optical can design and fabricate microlenses that are: refractive diffractive anamorphic aspherical spherical positive (convex) negative (concave)
Lenses can be either refractive or diffractive and can be as small as 15 microns diameter. Using standard materials such as fused silica and silicon and newer materials such as Gallium Phosphide and Calcium Fluoride a wide variety of lenses can be made. Lenses can be made on one side with absolute alignment accuracies which allow each lens to be within 0.25 microns of it's ideal location and a front to back surface alignment capability that allows lenses on both sides of a substrate to be aligned to within 1 micron. Surface roughness values of 20 to 80 angstroms RMS are typical and the addition of AR coatings produces optics with very high transmission rates.
