Planoconvex lens

A flat convex lens has a convex surface on one side and a flat surface on the other, and has a positive focal length. It is usually used for applications such as reducing beam size, reducing focal length, or enlarging images. To reduce spherical aberration, when a planar convex lens is used for collimating beam focusing, the beam should be incident on the surface of the lens; When used for point light source collimation, the beam is incident on a plane. Flat convex lenses are commonly used in imaging or beam collimation applications, and coated lenses are also widely used in visible and near-infrared applications.
