Aspherical lens Optosigma Corporation

These lenses are ideally suited to condensing and light collection applications. For these purposes it is necessary to locate the optic as close as possible to the source or detector in order to benefit from a large numerical aperture collection cone. These aspheric lenses are flat or convex spherical on one side and have a steep aspheric on the other side.

The lenses are molded and polished from high quality crown optical glass. Coating is not recommended since coatings work poorly on steep aspherics as the angle of incidence is widely variable across the diameter of the lens.
