Techspec Precision Aspheric Lenses

Edmund Optics has introduced its Techspec Precision Aspheric Lenses, designed to focus light, while they eliminate spherical aberration from divergent light sources. Designed and manufactured by Edmund Optics, Precision Aspheric Lenses are ideal for applications including focusing the output of laser diodes.

RoHS compliant Techspec Precision Aspheric Lenses feature precision aspheric designs that minimize spherical aberration, which decreases laser spot size and maintains 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.

Techspec Precision Aspheric Lenses have been computer optimised to eliminate spherical aberrations and minimise higher order aberrations. The lenses offer available prescription data for easy integration into a wide range of optical systems.

 

Techspec Precision Aspheric Lenses are available uncoated or with a VIS coating, which provides less than 1.5 per cent reflection from 425-675nm, and a NIR coating, providing less than 1.5 per cent reflection from 600-1,050nm. They are offered in 78 models with diameters from 10 to 50mm and numerical apertures from 0.50 to 0.83.
