Press Release Summary:
Available in 9 versions with diameters of 9.0, 12.5, or 25 mm, TECHSPECÂ® Aspherized Achromats bridge gap between color-corrected achromats and spherical aberration corrected lenses. Second surface of doublet lens is fused to molded polymer aspheric surface, which minimizes wavefront errors present in typical achromats while boosting numerical aperture. Typical applications include fiber optic focusing or collimation, image relay, inspection, and beam expanders.

Edmund Optics Introduces Aspherized Achromats
April 1, 2008, Barrington, NJ. Edmund Optics® announces the availability of TECHSPEC® Aspherized Achromats, which bridge the gap between color-corrected achromats and spherical aberration corrected aspheres. Typical applications include: fiber optic focusing or collimation, condensing systems, image relay, inspection, scanning, beam expanders, and high numerical aperture imaging.
Achromatic lenses typically consist of cemented assembly of a low index and high index lens, matched for their ability to reduce chromatic aberration, but not necessarily matched to correct for focusing aberrations inherent in spherical lenses. Meanwhile, aspheric lenses excel at correcting spherical aberrations, but are not capable of addressing chromatic aberrations. TECHSPEC Aspherized Achromats correct for both types of aberrations.
The second surface of the doublet lens is fused to a molded polymer aspheric surface. This surface reduces the wavefront errors present in typical achromats while boosting numerical aperture. Nine versions of the lens are available, with diameters of 9.0, 12.5, or 25 mm, and effective focal lengths ranging from 12 to 50 mm.
"The benefits to both achromat and asphere applications are tremendous. For customers who use achromats, a potential order of magnitude performance improvement is achievable at a very small cost premium. For customers who integrate precision aspheres, a potential order of magnitude cost reduction is achievable at a very small performance premium," explained Gregg Fales, Product Line Manager.
These low-cost color-corrected aspheric lenses have been awarded an honorable mention in the 2008 PhAST/Laser Focus World Innovation Awards Program. Additional information is available at www.edmundoptics.com/aspherized.
