Plano-Concave Lenses

Introduction of Plano-Concave Lenses

A plano concave lens is a lens that is flat on the one side and concave on the other. Plano concave lenses converge parallel light, correct the deflected light and convert point light sources into parallel light. When light enters from the concave surface of the plano concave lens, the light will converge to a point on the concave surface. When a point light source enters from the plane of the plano concave lens, the light will be turned into a parallel beam. The focal length of a plano concave lens can vary depending on wavelength. Plano concave lenses can be used in transmitters, detectors and lasers.

Spherical lens features

Spherical lens processing types

Plano-convex lenses, double-convex lenses, plano-concave lenses, double-concave lenses, positive meniscus lenses, negative meniscus lenses, flat lenses, single-cap lenses, double-convex double-step lenses,

Plano-concave lens scatters parallel light outward. The focal length of the plano-concave lens is negative, and the spherical aberration is also negative, which can be used to correct the aberration, spherical aberration, coma, and distortion of other lenses. Similar to a plano-concave mirror, the sides generally face the far object surface or infinity. The plano-concave lenses produced by Dingxinsheng Optical are usually made of K9 glass, and their anti-reflection coating is aimed at the wavelength range of 400-700 nanometers. There are also UV quartz as the base material for processing. When UV quartz is used as the base material, it has good transmittance and low thermal expansion coefficient in the ultraviolet region, and can be coated with UV AR film for use in special circumstances.
