Artifex Engineering Datasheets for Spherical Lenses

Spherical lenses, also known as singlets, are transparent optical components consisting of one or more pieces of optical glass with surfaces so curved that they serve to converge or diverge the transmitted rays from an object, thus forming a real or virtual image of that object.  This area includes micro spherical lenses as well.

Product Name Notes
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.
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...
Plano-Concave (PCV) 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.
Plano-convex 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...
