NEW COMPUTAR TEC-M55 55mm f2.8 These lenses typically sell for over $350.00 from a dealer. These items are brand new components of a system we used to sell. The Computar TEC-M55 is a 55mm F/2.8 Precision Telecentric lens designed for close up work with minimal parallax error. It features locking screws and a C type lens mount. Made for use with a 2/3-inch or smaller CCD format camera. * 0.14 Meter Minimum Object Distance * ±12.5mm Depth of Field at 0.5X * Ideal for Measurement Applications Telecentric lenses yield constant magnification over a range of working distances, virtually eliminating viewing angle error. The 55mm focal length telecentric lens allows ±12.5mm of object movement (at 0.5X magnification) before a 1% error in image scale occurs, while conventional lenses permit typically ±1.7mm of movement under the same conditions. This lens is ideal in machine vision applications requiring accurate measurement of three-dimensional objects with slight height variations. By eliminating the perspective distortion and magnification error inherent in conventional lenses, they yield dimensionally accurate images that are easily interpreted by software.
