The Zoom 7000 is a close-focusing macro video lens with a working distance of 5 inches to infinity. This versatile lens is compatible 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 assurance, biomedical imaging, 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 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 Bayonet Mount Zoom Lens (3CCD Camera) (1-11898) or a Zoom 7000 locking sleeve (1-11736).
