Telecentric Lenses are used in imaging systems to make objects appear to be the same size independent of their location in space. Telecentric Lenses remove the perspective or parallax error that makes closer objects appear to be larger than objects farther from the lens, increasing measurement accuracy compared to conventional lenses. Telecentric Lenses are ideal for use in a variety of applications, including metrology, gauging, CCD based measurement, or microlithography.
