Features

Advantage of Aspheric Lenses

In applications that require large acceptance angles, such as light gathering for illumination, spherical lenses are unsuitable due to spherical aberration, or the effect of refractive power of a spherical surface becoming greater with increasing aperture. Aspheric lenses maintain constant focal length or very high NA, avoiding the need for multiple elements to correct spherical aberration. This simplifies system design by reducing weight and component count. It also results in less transmission loss, and less ghosting due to having fewer surfaces. The primary drawback of aspheric lenses is off-axis performance is poor. This is not a problem for coupling to and from optical fibers or collimating light sources, but aspheric lenses are not usable over a wide field of view.

Molded Glass Aspheric Construction

These Geltech lenses are made from Corning C0550 glass, which features low dispersion (Vd=50.40). Typical applications include fiber coupling, laser diodes, medical lasers, optical data storage, and barcode scanners.  Mounted versions with a 304 stainless steel holder are also available.

We offer a full range of optical lens mounts to meet various experimental requirements. Below lists the recommended mounts for spherical lenses of standard sizes. Please see our Lens Mount Guide for additional information.

Note: besides the diameter, please check the Edge Thickness (Te) specification of the lens and the lens mount to ensure compatibility before purchasing.
