Off-the-Shelf Aspheric Optics in Optimal Sizes
BARRINGTON, N.J., March 23, 2006 -- Aspheric lenses offer optical designers excellent control of light-ray refraction over the lens’ whole surface, making it possible to produce optical systems with higher performance in more compact packages than is possible with more conventional lenses. The catch is that accurately fabricating aspherical surfaces requires specialized equipment and expertise, putting the technology out of reach for most optical-system designers. Optical and imaging components manufacturer Edmund Optics said it has changed that situation by offering a line of high-performance aspheric optical components in the sizes most useful to optical system designers.

Edmund has the expertise and equipment to produce aspherical optical components from 10 to 200 mm diameter with e/20 accuracy. Not only does Edmund offer its customers access to this technology, they have used it to fabricate a stock of reasonably priced Tech Spec aspheric lenses with clear apertures from 15 to 25 mm and effective focal lengths from 11.25 to 37.5 mm. Because these lenses have aspheric surfaces, they can provide sharp images at optical speeds up to ƒ/0.75.

The company said its state-of-the-art environmentally controlled aspheric manufacturing facility houses advanced aspheric grinding and polishing equipment coupled with magnetorheological finishing technology for super-accurate lens polishing. This facility produces high-departure aspheric geometries (>100 µm departure) that Edmund said can be manufactured rapidly and cost effectively in glass, ceramic or crystalline materials.

According to Edmund, its commercial off-the-shelf Tech Spec lenses offer the benefits of an aspheric design performance combined with the manufacturing precision of state-of-the-art grinding and polishing equipment. With the available prescription data, optical designers can easily integrate these lenses into complex state-of-the-art optical systems. Featuring high lens speeds for optimum light gathering and focusing performance, these lenses are computer optimized to eliminate spherical and minimize higher order aberrations.

GLOSSARY
aspheric
Not spherical; an optical element having one or more surfaces that are not spherical. The spherical surface of a lens may be slightly altered so as to reduce spherical aberration. Aspheric surfaces are frequently, but not necessarily, surfaces of revolution about the lens axis.
grinding
The process in the manufacture of an optical system that gives it the required geometric shape.
lens
A transparent optical component consisting of one or more pieces of optical glass with surfaces so curved (usually spherical) that they serve to converge or diverge the transmitted rays from an object, thus forming a real or virtual image of that object.
optical
Pertaining to optics and the phenomena of light.
polishing
The optical process, following grinding, that puts a highly finished, smooth and apparently amorphous surface on a lens or a mirror.
