Spherical Singlet lenses are transparent optical components consisting of one piece of optical glass.

Their surfaces are so curved (usually spherical) that they serve to converge or diverge the transmitted rays from an object, thus forming a real or virtual image of that object.

We offer a wide range of custom and standard spherical singlet lenses for almost any application.

Plano-convex spherical lenses have a positive focal length. They are most suitable where one conjugate is more than five times the other, e.g. in sensor applications or for use with nearly collimated light.

They are also used in applications where both conjugates are on the same side of the lens, e.g. as an add – on lens to increase the numerical aperture.

Double-Convex (DCX) lenses are most suitable where the conjugates are on opposite sides of the lens and the ratio of the distances is less than 5:1, e.g. as simple image relay components.

Plano-Concave (PCV) spherical lenses have one flat and one inward curved surface. PCV lenses have a negative focal length and are used for image reduction or to spread light.

Double-Concave (DCV) lenses have two inward curved surfaces. DCV lenses have a negative focal length and are used for image reduction or to spread light.
