Plano concave spherical lens
A plano-concave lens bends the parallel input rays so that they diverge from each other on the output side of the lens and therefore has a negative focal length. The spherical aberration of a plano-concave lens is negative and can be used to balance the aberration produced by other lenses.
A plano-concave spherical lens consists of a flat surface and an inward curved surface with thicker edges than the center. It is ideal for beam expansion, light projection and focal length expansion of optical systems.

Spherical lens is the most basic optical component of the microscope optical system, the objective lens, eyepiece and focusing lens and other components are composed of single and multiple lenses. Depending on their shape, they can be divided into two categories: convex lenses (positive lenses) and concave lenses (negative lenses).
China Star Optics can provide different kinds of spherical lenses like plano concave lens, plano convex lens, achromatic lens. If you want to know more information about a plano-convex lens/mirror, such as the use and refractive index of a plano-convex lens, please contact us.
