Edmund Optics now offers a new line of TML-HP (High Power) Telecentric Measuring Lenses. Telecentric lenses have been designed to replace lenses that give inaccurate or inconsistent readings due to perspective errors that yield variations in magnification through the depth of field. The lenses are ideal for both on-line and off-line production environments that require accurate measurements.
The telecentric lenses offer a quality, compact, cost-effective solution for replacing standard lenses with fixed focal lengths. They build on Edmund Optics’ established TML Telecentric series, offering additional features including smaller fields of view, a high numerical aperture, and higher magnifications of 1X, 2X, and 4X. The 2X and 4X models also feature a double-telecentric design, giving the sharpest image while minimising errors to give the most accurate measurements.
The simplified non-focusing mechanical design offers adjustable iris control. A standard C-Mount camera interface increases flexibility of use on half-inch camera sensors. They contain a front filter thread for the addition of filters, polarisers or various types of illumination.
