The
Zoom 7000 is a close-up focusing macro video lens
system which is versatile and specifically designed
to be used in applications where objects over 2"
in diameter must be imaged. It offers unsurpassed
clarity and parfocal zoom capabilities and is compatible
with cameras 2/3” or smaller.
The
Zoom 7000 is ideal for quality assurance or assembly
applications 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 manufacturing failure.
The
Zoom 7000 offers a 6:1 zoom ratio or a 6X magnification
power over a focal range of 18mm to 108mm. It comes
with a close-up lens for imaging at distances from
5" to 12".
When
the close-up lens is removed from the Zoom 7000 System,
the working distance extends from 24" to infinity.
Focus and aperture control are standard Zoom 7000
features. Navitar also makes a version of the Zoom
7000 for 3-chip cameras with a bayonet or C-Mount.
Example:
Object size = 100mm x 50mm and Camera format = 2/3"
Criteria:
All edges should be visible at low magnification and
high magnification should show the object at maximum
magnification.
Looking
at the chart, a 10" working distance would allow
a 108mm 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 magnification at high zoom.
