Unsurpassed Optical Performance
The optical system of the Zoom 6000 produces images of
the finest optical quality. Chromatic aberration and distor-
tion have been virtually eliminated. With the Zoom 6000
lenses, images are crisp and clear and display optimum
contrast with minimum flare over the entire field of view.
Manual or Detented for Calibrated Repeatability
The Zoom 6000 lenses are available in a manual design, as
well as a detented version for calibrated repeatability.
Motorized for Automation
If you are building highly automated systems, Navitar can
offer you a wide selection of motorized lenses and control
equipment. Please see the motorized section of the catalog.
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 magnification
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 (transfer)
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.
