Mounted Molded Glass Aspheric Lenses
Mounted Molded Glass Aspheric Lenses
These mounted Geltech® molded glass aspheric lenses are a very economic choice for collimating or focusing light at high magnification. They are made from low dispersion materials and are suitable for applications include fiber coupling, collimating laser diodes, and laser scanning.
- Threaded stainless steel mounts
- Aspheric surface reduces spherical aberration
- Visible or NIR anti-reflective coatings
- Economical choice for collimating or focusing light See All 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
Stainless Steel Mounted Version
These mounted Geltech lenses feature a stainless steel 304 holder with a threaded exterior, M9x0.5 or M12x0.5. The numerical aperture is the same as the corresponding unmounted lens, but the working distance is slightly different. Aspherical Lens Adapters UPA1-AS9 and UPA1-AS12 are available to mount them into standard 1 in. optical mounts.
