Raising the Standard for Optical Excellence

The Highest Combination of Zoom Range and Resolution in a State-of-the-Art Optical System
Navitar’s 12X Zoom is the next generation in video zoom optics. With a zoom ratio of 12:1, a zoom range of 0.58X to 7X and a dynamic magnification range of .07 to 583X, the 12X is the only single lens system to provide such a high combination of zoom range and resolution.  This outstanding combination of video clarity and zoom range, coupled with unprec-edented field coverage, means that you will now be able to view a wider range of parts with a single video inspection system.

Flexible by Design The 12X Zoom system is designed on a modular basis, offering optical quality and mechanical flexibility. This interchangeabledesign,combined with a wide range of lens adapters and attach-ments, allows you to easily choose the magnification, field of view and working distance that best suit your viewing needs.  In fact, the 12X Zoom system is even com-patible with existing Zoom 6000 adapters.

All 12X Zoom models have a 12X parfocal zoom lens system with a high N.A. (0.018 - 0.1) to achieve higher resolution and improved contrast.  Working dis-tance can be varied from 32 mm (1.25”) to 341 mm (13.4”) and fields of view can be achieved from 0.006 mm to 85.71 mm.Designed to IncreaseProductivityThe 12X Zoom system is ideal for use in the inspection of a wide range of products, such as semiconductor chips, PC boards and life science applications. It increases productivity by eliminating the need to change components to view a wider range of parts.  It’s easy to use and displays crisp, clear images on any monitor for individual or group viewing.

Unbeatable Accuracy

Our 12X Zoom delivers unbeatable accuracy and repeatability for even the toughest die bonding, life science, and FPD inspection applications. Superb Navitar optics deliver remarkably high contrast, high resolution video images.  The 12:1 zoom ratio provides an incredible magnification range that allows both high magnification for preci-sion measurement and inspection, as well as low magnification for a wider field of view.  Bonding,probing, scribing and aligningapplications can all be performed better and more accurately than with any other zoom lens on the market.

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 apparentdifferences 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.
