West Coast Tech Limited Double-Convex Lens

Like Plano-convex lens, double convex lenses have positive focal lengths and form both real and virtual images. Symmetry is assured by finishing both surfaces with the same tool. Because of symmetry, aberrations including coma, distortion and lateral chromatic aberration almost exactly canceled at unit conjugate radio. Double convex ...

Plano convex lenses have positive focal lengths, converge incident light, and from both real images (as might be focused in a piece of paper), and virtual images (as are seen through the lenses when they are used as magnifiers). They are widely used in telescopes, collimators, optical transceivers, magnifiers, radiometers and ...

Ross Optical Bi-Concave Lenses
Compare
Bi-concave lenses have two inward curved surfaces. These lenses have a negative focal length. Our catalog bi-concave lenses have an identical curvature on both sides of the lens and are therefore symmetric. At unit conjugation, coma and distortion are cancelled out due to the symmetry. They are used to diverge incoming light or ...

Freeforms are optical shapes or optical surfaces that are designed with little to no symmetry. Manufacturing a freeform is similar to that of a highly complex asphere; surface form and local slope change are all factors that influence the complexity of the shape and the manufacturing process used.
