The Schneider Group (Hauppauge, N.Y.)has introduced Object-Sided Telecentric Lenses for high-accuracy non-contact metrology applications in which cost and weight are primary considerations. Weighing as little as 21.8 oz. (and up to only 28.5 oz.), Schneider's Object-Sided Telecentric Lenses are ideal for applications in which an electronic image processing machine must move and position the lens quickly and precisely to optically measure 3D components. Their high aperture (NA 0.1) provides good image quality even under low light conditions.Based on the design of Schneider prime lenses, Schneider's new Object-Sided Telecentric Lenses produce ultra-low geometric distortions, and maintain a constant magnification within the specified depth of field. They image only features that are orthogonal to the lens, which results in high overall measurement performance, particularly at the extremes of the field of view. Schneider Object-Sided Telecentric Lenses are available in four different magnifications (0.27X, 0.39X, 0.62X and 0.79X), and are designed to work with 2/3-inch format CCD cameras. The 0.79X lens can also accommodate 1-inch format CCD cameras. Each lens features a fully-adjustable iris control, and an integrated front thread to accept M72 x 0.75 filters. An optional lens mount facilitates easy and precise positioning of the lens and locks down the lens for increased system stability. www.schneiderindustrialoptics.com
