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.
Benefits 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.

Our machine vision telecentric lenses include the 12X Telecentric Zoom system,
the TC-5028 and TEC-M55 telecentric video lens. Our single-sided lenses, the
Invarigon-R™, Macro Invaritar™, ELWD Macro Invaritar™ and
Invaritar Large Field telecentric lenses are available with several different
accessories that enhance the performance of the lenses. They include teleconverters,
right angle attachments, fiber bundle collimators and lens mounting brackets.
Our Double-Sided series of lenses are telecentric in both the object and image
space and have optional illumination accessories to provide a bright, even illumination
that will compliment the performance of the lenses.
