High Precision Aspheres
OptoSigma is proud to offer a line of high-precision aspheric lenses. These lenses have an aspheric surface on the front and a Plano surface on the rear and can be used to simplify your optical system and help reduce spherical aberration. Our lenses are uncoated but can be customized with one of our AR coatings. If you need a custom aspheric lens shape, contact us direct.
