Plano Concave Lens

Plano-concave Lenses present a concave surface and a Plano surface. They have a negative focal length and are used for image reduction or to spread light. These lenses diverge to 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.
