Bi-Convex Lens

 
Biconvex lenses have a positive focal point and are mainly used for image magnification and light collection applications.

Compared to a plano-convex lens, the power to refract a light beam is stronger, so it is suitable for making compact optical systems such as illumination systems, telescopes, monoculars, microscopes, binoculars, cameras, and projectors.

The products shown are uncoated, but we also accept custom orders for anti-reflection coating and other coating. Please contact us for the coating simulation data and the pricing.

■Applications
 Magnifying lens
 Condensing lens
 Objective lens
 Magnifying glass
 A biconvex lens is used to create a virtual image when the lens is viewed close to the eye and a real image in the case of photographic film or optical sensors
 These lenses are also used as burn glasses.
 Image relay lens
