Edmund Industrial Optics Announces Telecentric Lenses for Industrial Applications



March 2, 2002, Barrington, NJ - Edmund Industrial Optics (EO) of Barrington, New Jersey is providing MVO Telecentric Lenses designed specifically for industrial machine vision applications. Telcentric lenses are important tools for machine vision systems and metrology applications because they correct for perspective error.

The MVO (Machine Vision Optics) Telecentric Lenses are available in four magnifications and provide both high resolution and low distortion. They can be used with CCD sizes as large as 2/3 inch, and provide less than 0.1 telecentricity. A given magnification can be obtained anywhere within the specified working distance range, simply by refocusing.

The following combinations of magnification, working distance, and field of view (FOV based on using a 1/2 inch format CCD) combinations are available:

Magnification: 0.13X, working distance: 150 to 200 mm, FOV: 49.2 mm.
Magnification: 0.25X, working distance: 175 to 200 mm, FOV: 25.6 mm.
Magnification: 0.5X, working distance: 125 to 150 mm, FOV: 12.8 mm.
Magnification: 1X, working distance: 115 to 140 mm, FOV: 6.4 mm.

All the lenses have a front filter thread for the addition of color filters, polarizers, or other mounted components. Both the aperture and focusing adjustment positions can be fixed by a set screw to remain secure in high-vibration environments.
