Telecentric Format Lenses

Fixed Focal Length Lens with Manual Focus and Iris

The Navitar TC-5028 telecentric lens is a 50 mm F/2.8 telecentric lens which reduces or eliminates viewing angle error and magnification error while providing high resolution and contrast with low distortion. This compact, lightweight lens can be used with 1/3", 1/2" and 2/3" format cameras and is usable from 0.5X to 1.0X, 1:1.

Machine vision has made the telecentric lens popular because conventional lenses are often unable to accurately portray objects which are slightly out of focus or at different distances from the lens. Constant perspective and magnification are maintained with a telecentric lens, so the size of the image will not change even if these problems do occur.

Other focal length lenses are being designed. Please call for more information.
