Comparing with ordinary lenses ASPHERIC lens have well designed curves to reduce aberrations and make easy to build lens with higher quality and lower weight. Incorporating anon-spherical lens, an optical system will have a much smaller image variance ,a larger relative aperture, a wider field of view and according a higher image quality .
Using non-spherical optical system for IR thermal cameras, a single non-spherical lens can replace multiple spherical ones . |
