BARRINGTON, N.J., Oct. 13, 2016 — Aspheric LensesDesigned to focus light while eliminating spherical aberration from divergent light sources, the TECHSPEC Precision Aspheric Lenses from Edmund Optics Inc. have been computer optimized.

The lenses decrease laser spot size and maintain high power per area. Aspheric lenses can increase the numerical aperture of a lens and may also reduce the number of elements needed in a multi-element system, potentially reducing overall system weight, increasing throughput and simplifying assembly. Featuring low ƒ/numbers for optimal light gathering performance, the lenses offer available prescription data for easy integration into a wide range of optical systems.

The lenses are available uncoated or with a VIS coating, which provides less than 1.5 percent reflection from 425 to 675 nm, and a NIR coating, providing <1.5 percent reflection from 600 to 1050 nm. They are offered in 78 models with diameters from 10 to 50 mm and numerical apertures from 0.50 to 0.83.
