Optical lens/plano concave lens/BK7 Lens

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 plano convcave lens with tighter manufacturing tolerances.

World hawk can offer many kinds of normal cylindrical lenses.Including Plano-Convex, Plano-Concave, Bi-Convex, Bi-Concave, Meniscus, Aspherical Cylindrical lens, Toroidal mirror etc.. Plano concave cylindrical lens is a kind of lens

which includes a cylindrical concave face and a plano surface. Plano-concave cylindrical lenses provide uni-axial negative imaging for anamorphic beam expansion and a wide range of applications.

Application:

Plano concave cylindrical lenses are used in cases requiring magnification in one dimension only, such as in transforming

a point image into a line image or changing the height of an image without affecting its width.The functions is similar to plano-convex cylindrical lenses.
