ASPHERICAL PRECISION LENSES

Custom precision lenses are a key optical component for many transmission and imaging applications in the aerospace, security, defense, machine vision, health care, and life science industries. G&H manufacture custom precision lenses for imaging, focusing, collimation and illumination, using standard polishing and grinding techniques, as well as single point diamond turning and MRF®. We take a design-for-manufacture approach to lens production, facilitating the production of cost-effective, high quality custom precision lenses. 
Our lens processing capabilities include CNC generating, grinding, and polishing. We polish spherical, semi-spherical, and aspheric lenses. 5-axis grinding and polishing machines are utilized for manufacturing high precision aspheric surfaces on optical glass. Single point diamond turning is used for aspheric and diffractive optical elements.  A unique, stand-out capability for G&H is our ability to manufacture complex shapes on lenses, such as step profiles or off-axis shapes.
