A biconvex lens has a convex surface and a double surface, and has a positive focal length. It is usually used for related applications such as beam reduction, focal length reduction, or image enlargement. In order to reduce spherical aberration, the biconvex lens is used to collimate the 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 beam is incident on both sides. A biconvex lens focuses 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. We provide biconvex lenses with AR coating. Germanium, silicon or zinc selenide substrates are suitable for infrared applications, and fused silica is suitable for ultraviolet applications.

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.
