Calibration-Grade Lenses
Oct 2010
Edmund Optics Inc.Request Info
BARRINGTON, N.J., Oct. 14, 2010 — TechSpec calibration-grade precision aspheric lenses manufactured by Edmund Optics Inc. improve the efficiency of low-light-level detection systems and provide good off-the-shelf performance.

The high-numerical-aperture polished lenses deliver aspheric surface accuracy of 0.25 µm rms and offer improved aspheric surface figure, surface quality and centering specifications over the company's regular precision aspheric lenses. The uncoated lenses are available in 25- and 50-mm diameters, with numerical apertures of 0.50 and 0.66, making them suited for integration into R&D as well as OEM applications, and for applications requiring a compact optical path, where space is at a premium.

The individually serialized lenses include a complete metrology data package. This test data package includes a surface profile performed on a precision Taylor Hobson Talysurf profilometer, an interferogram of the spherical surface, and tested values for diameter, center thickness and centration. Custom-designed calibration-grade precision aspheric lenses as well as coating requirements and volume pricing are available upon request.

The lenses are in-stock and available for immediate delivery.
