VZM 100i

Edmund Optics

Edmund Optics has released the VZM 100i video zoom microscope. The VZM series are parafocal zoom lens systems for video cameras. The system is suitable for inspection systems that need to handle a wide range of object sizes without changing working distance.

The VZM 100i features a compact 28mm diameter removable mount with optional zoom lock adapter and works with camera sensors as large as 2/3-inch. It offers a 0.25x primary magnification, a 4:1 zoom ratio, and a horizontal field of view of 25.6mm when using a 2/3-inch sensor. Its working distance is 175mm with resolutions up to 70 lp/mm, and it offers a greater depth of field than other members of the VZM family.

As with other lenses in the family, the VZM 100i features a rack-and-pinion focusing movement and parafocal design to eliminate the need to refocus when changing zoom levels. The i-series also offers front threading for filters and a locking iris.

Edmund Optics - telecentric lenses

TML-HP

Edmund Optics

Edmund Optics now offers a new line of TML-HP (High Power) Telecentric Measuring Lenses. Telecentric lenses have been designed to replace lenses that give inaccurate or inconsistent readings due to perspective errors that yield variations in magnification through the depth of field. The lenses are ideal for both on-line and off-line production environments that require accurate measurements.

The telecentric lenses offer a quality, compact, cost-effective solution for replacing standard lenses with fixed focal lengths. They build on Edmund Optics’ established TML Telecentric series, offering additional features including smaller fields of view, a high numerical aperture, and higher magnifications of 1X, 2X, and 4X. The 2X and 4X models also feature a double-telecentric design, giving the sharpest image while minimising errors to give the most accurate measurements.

The simplified non-focusing mechanical design offers adjustable iris control. A standard C-Mount camera interface increases flexibility of use on half-inch camera sensors. They contain a front filter thread for the addition of filters, polarisers or various types of illumination.
