An aspheric lens is a single
element optical component with one aspheric convex
surface and one plano or sperical convex surface.
Characterized by f-numbers less than 10, aspheres
provide maximum energy throughput over a limited path
length. Although not designed for imaging applications,
they are ideal for use in illumination systems where
it is necessary to collect the focus as much light
as possible.
We can manufacture many different kinds of aspheric
lens, such as aspheric-plano, aspheric-concave, aspheric-convex
etc . |
