Description: PCV lenses have one flat side and one inward curving surface and negative focal length. They diverge incident light, and generally form virtual images, which could be seen through the lens. PCV lenses offer a very nearly minimum spherical aberration at negative-infinite or near-infinite conjugate ratios with the concave surface facing the longer object or image distance. These lenses are usually used as light beam expanders or to increase focal length in existing system.
