Telecentric Measuring Lenses

The Techspec Silver Series of telecentric measuring lenses offer a compact, cost-effective solution for replacing standard fixed focal length lenses. Telecentric lenses are ideal for both on-line and off-line production environments that require accurate measurements. Edmund Optics has designed this series of lenses to specifically replace lenses that give inaccurate or inconsistent readings. Telecentric lenses correct perspective errors that yield variations in magnification through the depth of field. The lenses offer superior image quality and less distortion than conventional fixed focal length lenses. This design yields more symmetrical images that are superior for software-integrated measurements. In combination with the high quality optics is a simplified non-focusing mechanical design with adjustable iris control. Telecentric designs require larger objective lenses in order to maximize the size of the object viewed for each magnification, thus the mechanical housing has been streamlined to accommodate the larger optics and to provide a reasonable amount of mounting surface. Each lens also has a standard front filter thread for use with Edmund colour filters, polarisers, protective windows, and illumination adapters for LED or fibre-optic ring guides. Unique twin-ring mounting clamps are available separately.
