| 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
