Zoom 7000 is a close- focusing macro video lens which is versatile
and specifically designed to be used in applications where objects
over 1" in diameter must be imaged. It offers unsurpassed clarity
and parfocal zoom capabilities and is compatible with cameras 2/3"
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.
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 a version of the Zoom 7000 for 3-chip cameras with a
bayonet or C-thread mount (part # 1-11898).
Example . . . . . . . . . . . . . . . . .
size = 100 mm x 50 mm
Camera format = 2/3"
All edges should be visible at low magnification and high magnification
should show the object at maximum magnification.
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 100
mm wide and would provide maximum magnification at high zoom.
