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.
