Edmund Optics Announces Off-the-Shelf Aspheric Optics

23 March 2006 (Barrington, N.J.) − 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. Edmund Optics 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 mm diameter to 200 mm diameter with 1/20 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(TM) aspheric lenses with clear apertures from 15 mm to 25 mm and effective focal lengths from 11.25 mm to 37.5 mm. Because these lenses have aspheric surfaces, they can provide pin-sharp images at phenomenal optical speeds up to f/0.75!

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

Edmund's commercial off-the-shelf (COTS) TECH SPEC(TM) Precision Aspheric 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.
