China Dia15mm B270 Uncoated Optical Aspheric Lenses

Dia15mm B270 Uncoated Optical Aspheric Lenses

Aspherical 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.
