Aspheric lenses are formed using either CNC machining or molding using glass or plastic as the substrate. These lenses have surface profiles such as hyperboloid, paraboloid, acylinder or other higher order surface profiles. Aspheres are typically used to correct spherical aberration or to simplify the number of elements in a design or both. We also manufacture custom solutions in case one of our many standard lenses do not meet your requirements.
High Precision Aspheres
OptoSigma is proud to offer a line of high precision aspheric lenses fabricated by Asphericon. 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 can be ordered uncoated or with one of our AR coatings. If you need a custom aspheric lens, contact us direct.
Aspheric Condenser Lenses
An aspheric condenser lens is used to focus collimated light (condense) with a short focal length in a single lens element with minimal spherical aberration. These lenses have an aspheric surface on one side and either plano or spherical surface on the other. OptoSigma offers anti-reflection coatings to help reduce surface reflections losses.
