Navitar offers a family of high-performance telecentric lenses for use in machine vision, metrology, and precision gauging applications. All provide low optical distortion and a high degree of telecentricity for maximum, accurate image reproduction, particularly when viewing three-dimensional objects.
Be nefits of Telecentric Lenses
One of the most important benefits of a telecentric lens is that image magnification does not change as object distance varies. A telecentric lens views and displays the entire object from the same prospective angle, therefore, three-dimensional features will not exhibit the perspective distortion and image position errors present when using a standard lens. Objects inside deep holes are visible throughout the field, undistorted, therefore, telecentric lenses are extremely useful for inspecting three-dimensional objects or scenes where image size and shape accuracy are critical.
