Plano-convex lens



It has a positive focal length and is most suitable where one conjugate is more than five times the other, e.g. in sensor applications or for use with near collimated light, also where both conjugates are on the same side of the lens, e.g. as an add-on lens to increase the numerical aperture.

Photonchina’ plano-convex lenses have excellent shape, with best centration and flatness, and can be used either for focusing collimated light or for collimating a point source. Our plano-convex lenses are fabricated from N-BK7, Silicon, UV-fused silica, Sapphire, Calcium Fluoride, Magnesium Fluoride.
