A plano-convex lens has a convex surface and a flat surface with a positive focal length. In order to reduce spherical aberration, when a plano-convex lens is used for collimating beam focusing, the beam should incident on the surface of the lens. When used for collimation of point light source, the beam incident on the plane.
It is usually used for related applications such as narrowing the beam, reducing the focal length or enlarging the image.
Regular product specifications are listed below, we can also customize various specifications of flat convex lenses for customers.
