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. For more information, visit: www.edmundoptics.com; e-mail: [email protected]
