SCV lenses with two symmetric inward curving faces have negative focal length, diverges incident light and generally forms a virtual image. Like the PCV lenses, they are often used to expand light beam or to increase the focal length. These types of lenses are normally used in devices such as laser beam expanders, projection optics, etc. in combination with other lenses.
