Telecentric Lenses
Navitar Telecentric Lenses
Navitar o ers 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 im-
age reproduction, particularly when viewing three-dimensional objects.
Bene ts of Telecentric Lenses
One of the most important bene ts of a telecentric lens is that image magni ca-
tion does not change as object distance varies. A telecentric lens views and
displays the entire object from the same prospective angle, therefore, three-di-
mensional 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  eld, undistorted, therefore, telecentric lenses are extremely
useful for inspecting three-dimensional objects or scenes where image size and
shape accuracy are critical.
Choose the Best Lens Option for Your Needs
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 In-
varigon-R™, Macro Invaritar™, ELWD Macro Invaritar™
and Invaritar Large Field telecentric lenses are avail-
able with several di erent accessories that enhance
the performance of the lenses. They include telecon-
verters, right angle attachments,  ber bundle collima-
tors and lens mounting brackets. Our Double-Sided
series of lenses are telecentric in both the object and
image space and have optional illumination accesso-
ries to provide a bright, even illumination that will
compliment the performance of the lenses.

Telecentric Lenses
The World’s First Parfocal Telecentric Zoom Lens
The 12X Telecentric Zoom system allows users to reach a true telecentric
condition to within less than 0.3° while maintaining constant perspective
and magni cation. This means that even if the object is slightly out of
focus, the size of the image will not change. The 12X Telecentric Zoom
provides  eld coverage from 50 mm down to 4 mm and the coaxial illumi-
nation allows clear viewing, even when working with mirror-like surfaces.
Also available without coaxial illumination.
Wide Magni cation Range and Ultra Long Working Distance
In the past, a telecentric lens was de ned as having  xed magni ca-
tion. Not anymore! The Navitar 12X Telecentric Zoom lens allows you
to zoom in and focus over a wide variety of magni cations with a higher
level of accuracy than you ever thought possible. The 12X Telecentric
Zoom provides adjustable focal lengths over a 0.16X to 1.94X magni ca-
tion range. You no longer have to be limited by telecentric lenses that
only o er  xed magni cation. Now you have  eld coverage from 50 mm
down to 4 mm at a 188 mm working distance.

Distortion < 0.1% for all magni cations. Working Distance = 188 mm for all magni cations.
12X Telecentric Lens Speci cations
No Need to Change Lenses
The easily adjustable  eld of view and magni cation allow
our Navitar 12X Telecentric lens to adjust to meet your
exact requirements. It’s no longer necessary to change
lenses, mix and match base lenses with attachment lenses
or recalibrate. One lens, the 12X Telecentric, really does
it all! Straight, as well as right angle, versions allow OEM
designers to best  t the systems to their mechanical design.
Wide Range of Applications
Speci cally designed for precise dimensional measurement
of objects or pattern recognition, the 12X Telecentric Zoom
has many applications. It’s ideal for measuring three-di-
mensional objects with deep features, such as well plates,
electrical connector pins, and other precision parts. It’s
also the perfect lens for viewing inconsistently placed parts
on a conveyer belt.

1. The maximum object dimensions shown in the table are 90% of the theoretical maximum dimensions, providing safety factor of magnication and alignment errors.
2. Lenses operated at smaller f/# may show reduced resolution, especially near the edge of the eld of view.
3. Depth of eld is calculated for a 30-µm allowable blur at the image (camera) plane at f/11 (for lenses with minimum operating f-number<f/16) or f/22 (for all others).
4. Teleconverters 59 LGZ 420 and 59 LGZ 415 cannot be used with certain types of 3-CCD color cameras.
Note: Distortion is less than 2% for all lenses. Contact Navitar for distortion characteristics for a specic lens.

providing a safety factor of magnication and alignment errors. For larger arrays, contact Navitar.

Single-Sided Telecentric Lens
Accessories
Teleconverters
When a closer view of objects is required, use a 59
LGZ-series teleconverter with your InvaritarTM large-
 eld gauging lens. Mounted between the lens and the
camera, these teleconverters increase magni cation by
up to 2.0×. Their compact size has minimum impact
on overall lens/camera length. Teleconverters increase
lens f-number and contribute to overall image distor-
tion. Teleconverters cannot be used with some 3-CCD
color cameras.
Navitar o ers several di erent accessories to enhance the performance of their Machine Vision telecentric lenses.
These include: teleconverters to increase magni cation, right angle attachments for viewing of objects up to 360
degrees about the optical axis,  ber bundle collimators to provide collimated backlighting and anodized mounting
brackets for proper mounting of the Invarigon-R™ and Invaritar™ lenses.
