OPTICAL COMPONENTS Aspheric Lenses Spherical Lenses Very high numerical apertures for effective energy collection and condensing Aspheric surfaces are molded, then polished Very attractive prices for demanding applications Made from high quality optical crown glass Cylindrical Lenses Lens Kits Achromatic Doublets Multi-Element Micro Optics Mirrors Prisms Substrates & Windows Beamsplitters Polarizers Filter & Apertures 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.
