The Plano Concave Lenses are made from BK7
material, which are manufactured with one concave surface and one plane
surface. These lenses have negative focal lengths. These lenses diverge
collimated incident light. They form virtual images which are seen through the
lens. They are often used to expand light or to increase focal lengths in
existing systems. We also offer precision grade
