    CaF2 Plano concave Lenses are made from CaF2 material. They present a concave surface and a plano surface. They have a negative focal length and are used for image reductinon or to spread light. These lenses diverge collimated incident light and form virtual images which are seen through the lens. They are often used to expand light or to increase focal lengths in existing systems.
