BK7 Double-Concave Lenses
Double concave lens(DCV) is similar with plano concave lens. The focus length is negative. It can make parallel light diverge outside. The two sides have same radius of curvature. Double convex lens generally used for expanding beam of light and projection etc. BK7 double concave lens has excellent transmittance from visible to near infrared wavelength (350-2000nm).

Plano-convex cylindrical lens
Plano-convex cylindrical lens
Plano-convex cylindrical lenses only focuses in one direction and has no focusing function in the other direction. The external dimensions of a plano-convex lens are similar, but only limited to a spherical mirror on one profile. A cylindrical lens can transform the light emitted by a luminous point into a line, and by placing two flat convex lenses perpendicular or intersecting with each other, surface light can be generated. The total focal length is the sum of each focal length.
