Silicon PCX Lenses

Photonics Spectra
May 2011
Edmund Optics Inc.Request Info
 
TechSpec silicon planoconvex (PCX) lenses manufactured by Edmund Optics Inc. are suitable for use in weight-sensitive infrared applications from 3 to 5 μm, for near-infrared imaging and infrared spectroscopy, with density less than half that of germanium or zinc selenide. The lenses feature precision-polished surfaces with a positive focal length and with one flat and one convex surface. They are designed for orientation with the plano (flat) surface facing toward the desired focal plane, are available in focal lengths from 25 to 250 mm and are offered uncoated. They also may be coated with a wide range of the company’s custom infrared coatings. The lenses are manufactured from low-density silicon and are suitable for use in the 1.2- to 7-μm wavelength range.
