Flexible by Design
The 12X Zoom system is designed
on a modular basis, offering
optical quality and mechanical
flexibility. This interchangeable
design, combined with a wide
range of lens adapters and attach-
ments, allows you to easily choose
the magnification, field of view
and working distance that best suit
your viewing needs. In fact, the
12X Zoom system is even com-
patible with existing Zoom 6000
adapters.
All 12X Zoom models have a
12X parfocal zoom lens system
with a high N.A. (0.018 - 0.1) to
achieve higher resolution and
The Highest Combination of
Zoom Range and Resolution
in a State-of-the-Art Optical
System
Navitar’s 12X Zoom is the next
generation in video zoom optics.
With a zoom ratio of 12:1, a
zoom range of 0.58X to 7X and a
dynamic magnification range of
.07 to 583X, the 12X is the only
single lens system to provide such
a high combination of zoom range
and resolution. This outstanding
combination of video clarity and
zoom range, coupled with unprec-
edented field coverage, means that
you will now be able to view a
wider range of parts with a single
video inspection system.

improved contrast. Working dis-
tance can be varied from 32 mm
(1.25”) to 341 mm (13.4”) and
fields of view can be achieved
from 0.006 mm to 85.71 mm.
Designed to Increase
Productivity
The 12X Zoom system is ideal
for use in the inspection of a
wide range of products, such
as semiconductor chips, PC
boards and life science applica-
tions. It increases productivity by
eliminating the need to change
components to view a wider
range of parts. It’s easy to use
and displays crisp, clear images
on any monitor for individual or
group viewing.
Key Terms for Matrix Charts
Depth of Field
The distance allowing acceptable
image definition to be maintained
without refocusing.
Distortion
Distortion is a variation in magnifica-
tion across the field of view.
Field
Field of view for respective
camera format (normally measured
diagonally).
Magnification
A measure of the apparent
differences in size between the
object and image.
Matching Pixel Size
Matching pixel size is that which will
permit the minimum feature size to
overlap two pixels.
MTF (lp/mm)
A measurement of the ability of an
optical system to reproduce (trans-
fer) various levels of detail from the
object to the image, as shown by the
degree of contrast (modulation) in
the image.
N.A. Image (high or low mag.)
Measurement at the image point of
the largest cone of light rays that are
exiting the optical system.
N.A. Object (high or low mag.)
Measurement at the object point of the
largest cone or number of light rays
that are entering the optical system.
Object to Image Distance (O-I)
Total distance from the object to the
sensor inside the camera.
Resolvable Features (microns)
Measurement of lens system’s ability to
image closely spaced points, lines and
object surfaces as separate entities.
Working Distance (W.D.)
Clearance between object and lowest
mechanical part of the system.
Unbeatable Accuracy
Our 12X Zoom delivers unbeatable
accuracy and repeatability for even
the toughest die bonding, life sci-
ence, and FPD inspection applica-
tions. Superb Navitar optics deliver
remarkably high contrast, high
resolution video images. The 12:1
zoom ratio provides an incredible
magnification range that allows
both high magnification for preci-
sion measurement and inspection,
as well as low magnification for a
wider field of view. Bonding,
probing, scribing and aligning
applications can all be performed
better and more accurately than with
any other zoom lens on the market.

Assumptions:
1. Minimum resolvable feature size is half of the threshold line pair limit. Calculation = 1/(3000 x Lens N.A.)
2. Matching pixel size is that which will permit the minimum feature size to overlap two pixels. Calculation = 1/2(Feature Size x System Magnification)
3. If the matching pixel size is greater than the camera pixel size, the system is “lens limited.”
4. If the matching pixel size is less than the camera pixel size, the system is “camera limited.”

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 perspec-
tive and magnification. 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 field coverage
from 50 mm down to 4 mm
and the coaxial illumination
allows clear viewing, even
when working with mirror-like
surfaces.
Wide Magnification Range
and Ultra Long Working
Distance
In the past, a telecentric lens
was defined as having fixed
magnification. Not anymore!
The Navitar 12X Telecentric
Zoom lens allows you to
zoom in and focus over a wide
variety of magnifications with
a higher level of accuracy than
you ever thought possible.
The 12X Telecentric provides
adjustable focal lengths over a
0.16X to 1.94X magnification
range. You no longer have to
be limited by telecentric lenses
that only offer fixed magnifi-
cation. Now you have field
coverage from 50 mm down
to 4 mm at a 188 mm working
distance.
No Need to Change Lenses
The easily adjustable field of
view and magnification 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!
Wide Range of
Applications
Specifically designed for pre-
cise dimensional measurement
of objects or pattern recog-
nition, the 12X Telecentric
Zoom has many applications.
It’s ideal for measuring three-
dimensional 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.

12X Telecentric Lens Specifications
Constant Perspective for the
Highest Degree of Accuracy
Navitar’s 12X Telecentric lens
is designed for “straight on”
viewing of objects across the
entire field of view. Images are
not distorted and features are
easy to examine. Conventional
lenses view objects at different
angles across the field of view.
This changes the viewing per-
spective and can distort the size
and shape of the object, making
it difficult to view features ac-
curately.
Constant Magnification
Reduces Magnification
Errors
Magnification in the Navitar
12X Telecentric, unlike conven-
tional lenses, is independent of
working distance. Magnifica-
tion remains constant regardless
of how close or far away an
object is from the camera. This
reduces magnifications errors
and greatly extends gauging
depths of field. Conventional
lenses, however, view objects
that are closer to the camera
as larger than objects that are
farther away.

• Wafer characterization.
• Laser beam profiling.
• Optical component
measurement and analysis.
•Fiber alignment and
inspection.
•Assembly and monitoring.
A list of all 12X NIR Zoom system components can be found on our website at
www.machinevision.navitar.com.
Transmission of 12X Zoom Lens
About Using NIR Lenses
The wavelength band just beyond the visible is known as Near Infrared
(NIR). NIR is the electromagnetic band of wavelengths between 0.7-1.5
microns (700-1550nm). When light strikes a glass surface, a portion is
bounced back, thereby reducing the strength of the transmitted image.
Apply this behavior to a zoom lens with many glass surfaces, and the
result is a severe reduction in image intensity. To counteract the loss, the
lenses are coated with materials that minimize this effect.
Note: Since NIR lenses are not operating within the visible spectrum,
the resulting image is slightly different than when using a standard 12X
system. The standard lens resolution limits of an NIR lens are based on an
assumed average wavelength of 0.5 microns and is inversely proportional
to wavelength (maximum MTF = 3000xNA in the visible wavelength).
Therefore, substituting a wavelength of 1.5 microns will reduce the
maximum resolution by a factor of 3. In practice, this means a slight
reduction of contrast at the higher wavelengths.
Lens focal lengths shift slightly with wavelength, which impacts the
Numerical Aperture (NA), which affects the depth of field (.0005/NA^2).
Generally, the NA is reduced, which produces a greater depth of field,
along with a reduction in maximum resolution. Standard NIR microscope
objectives are usually lower in NA, also reducing maximum resolution
values.

12X Zoom
Detented System
Navitar’s Detented 12X Zoom provides twelve
discrete detented positions in the zoom travel.
Nominal positions at 1X, 1.5X, 2X, 2.5X, 3X, 3.5X,
4X, 4.5X, 5X, 6X, 6.5X and 7X on the zoom scale
allow the end user to make an exact calibration
repeatable within 0.05%. To order a detented zoom
system, place a “D” after the standard part number.
Reticle Projector
The Reticle Projector (1-60068) provides a means
for superimposing a reticle (crosshair, micrometer
scale, custom graphic) over the video image on the
monitor. The information on the reticle must be
contained to the size of the sensor. For example, if
a 1/2” camera sensor is used, the reticle must have
the information in a 4.8 x 6.4 mm area to be seen
on the monitor. This reticle can then be used as
a targeting device for measuring, machining, etc.
(Reticles must be 21 mm in diameter and are sold
separately.)
Advantages of Using a Reticle
• Enables quick identification of minute
dimensions in small parts.
• Costs less than an electronic crosshair
generator.
• The lines can be calibrated at various mag-
nifications and assigned measuring values.
•Reticle pattern can be rotated on its center
line to align with workpiece.

12X Zoom Accessories
Right Angle (RA) Accessories
The RA mount (1-6080) introduces a 90° bend in the optical axis,
shortening the overall length of the system. The resulting image will
be mirrored, thus erect and read backwards
from right to left when viewed with a
camera. The 12X Zoom system uses the RA
adapters 1-60060 (.71X), 1-6118 (1X),
1-61997 (adjustable 1X RA), 1-6120 (2X)
and 1-6187 (5X).
Non-Inverting Right Angle
Accessories
The Non-Inverting RA mount (1-60165)
introduces a 90° bend in the optical axis.
The use of a penta prism results in an image
that is erect and reads left to right. The 12X
Zoom system utilizes the NIRA adapters
1-60172 (.67X), 1-60182 (1X Tele), 1-60175
(1X), and 1-60185 (2X), and 1-60188 (5X).
Object Side Right Angle Attachment
Navitar offers an object side right angle
attachment (1-51490) that is added to the
front of the 12X Zoom and can be used with
all lens attachments except for the 1-50015.
Adapter Plates
Navitar offers a variety of different microscope converter plates so you
can use your zoom system with Nikon, Olympus, Meiji, and Leica focus
mounts (see diagram at right for part numbers).
Auxiliary Viewing Port
The Auxiliary Viewing Port (1-60370) provides a second output port for an
additional camera or for direct vision using an eyepiece. A 50/50 beam
splitter cube is used for minimal image degradation. This assembly uses
the RA Adapters (1-60060, 1-6118, 1-6120, 1-6187) to provide a parfocal
image. Adapters are required in both vertical and horizontal viewing axis.
Laser Injection Port
Navitar’s Laser Injection Port (1-60380) provides a means of introducing
a laser beam into the Zoom 6000 system. It is normally used between the
end of the zoom lens and an infinity corrected objective so that the objec-
tive condenses the laser beam into a highly concentrated spot. A beamsplit-
ter cube, rather than a plate, is used to minimize aberrations. The port is
also useful for projecting targeting devices onto the object.

2X F-Mount Zoom Adapter
Navitar’s 2X F-mount adapter (1-62922) is designed for larger format
sensors (up to 30 mm diagonal). The adapter is configured as an F-
mount, but its T-mount interface permits switching to other common
flange formats. An RA version is available (1-63218).
Not recommended for use with the 12X Zoom System with sensors
over 16 mm.
A complete listing of 12X Zoom accessories can be found on our web
site at www.machinevision.navitar.com.

Differential Interference Contrast (DIC) Modules
Two Differential Interference Contrast (DIC) modules are
available from Navitar:
• the DIC Assembly Nikon-High Resolution module
(1-63726) and
• the original DIC Assembly module (1-63102).
Both modules can be used on any ultra coax version
(zoom or non-zoom) of the 12X Zoom.
DIC, when used with reflected light, can often be
interpreted as a true three-dimensional representation
of the surface geometry. It provides a clear distinction
between raised and lowered regions in the specimen
being viewed.
Using the DIC module in reflected light situations
Two polarizers, one in the illumination axis and one
in the viewing axis, are crossed at 90 degrees such that
when looking at a perfectly mirrored surface all light is
extinguished by the second polarizer.
A prism, made from two pieces of quartz, is then placed
between the illuminator beamsplitter and the objective.
Due to the optical properties of the quartz, the polarized
beam is split into two. The two beams, separated by a
Prism In Prism Out
Prism In Prism Out
minuscule amount, are polarized at 90 degrees to each
other and one beam is shifted in relation to the other -
a phase shift.
If the subject being viewed exhibits properties that
change the length of the optical path of either beam
(such as surface profiles, optical densities, etc.), both
beams will experience further phase shifts.
With transverse movement of the prism the phase shift-
ing performance of the prism may be accentuated and
the final image is modified. By adding a polarization
modifier, such as a 1/4 wave plate, after the illumination
polarizer, the final effects are modified further.
The DIC modules work with object side NAs ranging
from 0.05 to 0.50, with optimum performance in the
range from 0.15 to 0.4. Lens attachments, operating in
the above range will serve for macro applications. Any
infinity corrected objectives designed for incident light
will suffice for micro applications. Operating param-
eters, such as magnification and FOV, will be the same
as Navitar’s existing tables for the 12X Zoom system
being used.

Polarizers
Polarization is a contrast enhance-
ment technique that can reduce
back reflections and bring out
salient features not readily visible
with normal viewing.
If you choose to add a polariza-
tion option to your lens system, it
requires an illumination polarizer
(2-51485), an analyzer above the
zoom, a quarter wave plate (op-
tional), and a shorter version of an
Adapter (RA) because the analyzer
shortens the optical path by
50.8 mm.
Analyzer
When used in conjunction with a
polarized light source, an analyzer
(1-60816) allows for cross polar-
ization of the light in the imaging
system. This reduces reflections
that can deteriorate the image
quality. The analyzer must be used
in conjunction with the right angle
adapters.
Aperture Control
Lens systems can be designed with
an internal iris that can be manipu-
lated without cutting into the field
of view. The iris permits the reduc-
tion of image intensity at the image
plane, which reduces “blooming”
and other damaging artifacts. The
iris can also be closed down to
essentially “stop down” the lens
to reduce the Numerical Aperture
of the lens. This narrowing of the
light gathering cone produces a
significant increase in the depth of
field (the thickness of the envelope
at the object, where various object
heights are still in reasonable
focus).
To have an aperture control feature
designed into your system place an
“A” after the standard part
number.
Infinity Corrected
Objectives
Infinity Corrected Objectives can
be attached to the Zoom 6000
UltraZoom to increase the sys-
tem magnification and decrease
working distance. Navitar offers
Mitutoyo long working distance
objective lenses in magnifications
of 5X, 10X, 20X, 50X (1-60226,
1-60227, 1-60228 and 1-60229)
and Motic long working distance
objective lenses in magnifications
of 5X, 10X and 20X (1-62828,
1-62829, 1-62830).
