Plano-convex lenses have a convex surface and a flat surface, with a positive focal length, and are usually used for related applications such as beam reduction, focal length reduction or image enlargement. In order to reduce spherical aberration, the plano-convex lens is used to collimate the light beam to focus, the beam should be incident on the curved surface of the lens; when it is used to collimate the point light source, the light beam is incident on the plane. Plano-convex lenses focus light into a point. Commonly used for aiming and focusing of monochromatic light sources. When in use, face the convex surface towards the incident light.

Application areas: security, vehicle, digital camera, laser, optical instruments

Huizhou Yisu Photonics can produce: plano-convex lenses, plano-concave lenses, biconvex lenses, biconcave lenses, meniscus lenses, cemented lenses, cylindrical lenses, etc., with nearly ten years of optical product processing experience and a complete prism lens processing production line . Anti-reflection coating can be applied to reduce the reflection on the lens surface according to customer requirements. This can reduce the loss of light energy and make the imaging clearer.
