A lens with a curved, non-spherical surface. Used to reduce aberrations and achieve a more compact lens size. With a spherical lens, rays travelling from the lens periphery create the image before the ideal focal point and give a blurred image centre. Molded aspheres efficiently relay the energy from the light source into the imaging components of the product. Designers of slide projectors and movie projectors often employ aspheres in their condensing systems to maximize the brightness and quality of their projected images.
