Plano-Concave Lenses
Plano Concave Lens, 40mm Dia. x -63.5mm FL, AR Coated R<0.25%@780nm, N-BK7 Lens
The Plano-Concave Lens have one flat surface and one concave
surface. They have a negative focal length and are used to
diverge incoming light, or to increase focal length in an
existing optical system. They can be used in beam expanders and
projection systems.More details about Plano-Concave
