Property and Application

Plano-Convex Lens Positive focus length. Most suitable where one conjugate is more than five times the other. Also where both conjugates are on the same side of the lens. It is widely used for emitter, detector and laser.

Double-Convex Lens Double-Convex lens are comprised of two convex spherical. Positive focus length. It is widely used for projection system, imaging system and laser measurement system.

Double-Concave Lens Negative lens with the form most suited to producing diverging light or a virtual image, where the input light is converging. It is widely used for laser expanding system.

Plano-Concave Lens

Negative lens with the form most suitable where one conjugates is more than five times the other, e.g. producing divergent light from a collimated input beam. It is widely used for projection system, imaging system and laser measurement system.

Material:K9, fused silica
CNI can offer different kinds of notch filters upon your requests.
