The Zoom 7000 is a close-focusing macro
video lens with a working distance of 5
inches to infinity. This versatile lens is com-
patible with cameras 2/3” or smaller and is
specifically designed for use in applications
where objects over 1” in diameter must be
imaged. It offers unsurpassed clarity and
parfocal zoom capabilities over the entire
zoom range.
The Zoom 7000 is ideal for quality assur-
ance, biomedical imaging, or assembly ap-
plications where an easy-to-view, sharp and
true-to-life magnified image of your product
can mean the difference between a shippable,
top-quality end product and a costly manu-
facturing failure.
The Zoom 7000 offers a 6:1 zoom ratio
or a 6X magnification power over a focal
range of 18 mm to 108 mm. It comes with
a close-up lens for imaging at distances
from 5” to 12”. When the close-up lens
is removed, the working distance extends
from 24” to infinity. Focus and aperture
control are standard Zoom 7000 features.
Navitar also offers an 18-108 mm Bayo-
net Mount Zoom Lens (3CCD Camera)
(1-11898) or a Zoom 7000 locking sleeve
(1-11736).

Taken from 2/3”, 1/2”, 1/3” & 1/4” camera monitor systems with an approximate 10% overfi ll. All dimensions are in mm. Zoom adjustment comes with locking screw.
Iris and Focus adjustment can be modifi ed for locking screw upon request.
Features
• Working distance
5” to infinity.
• Parfocal over entire
zoom range.
• Highest mag. 1.1X
at 5” (at camera).
Example
Object size
=
100mm x 50mm
Camera format
= 2/3”
Criteria
: All edges
should be visible at
low magnification and
high magnification
should show the object
at maximum magnifica-
tion.
Looking at the chart
below, a 10” working
distance would allow a
108 mm wide object to
be imaged into a 2/3”
camera. Therefore,
something slightly less
than 10” would do for
an object 100mm wide
and would provide
maximum magnifica-
tion at high zoom.
