Edmund Optics, Inc.: Video Camera Inspection Zoom Lens

Wednesday, October 24, 2007

Edmund Optics® (EO), provider of precision optical components and tools, today announced a new addition to its TECHSPEC® VZM™ (Video Zoom Microscope) lens family: the VZM™ 100i. The VZM™ series are parafocal zoom lens systems for video cameras, ideal for inspection systems needing to handle a wide range of objects 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. The VZM™ 100i 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 resolution up to 70 lp/mm, and it offers an increased depth of field over 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.
