VZM™ Zoom Imaging Lenses enable inspection of a wide range of objects without the inconvenience of changing working distances. In addition, the parfocal zoom allows magnifications to be easily changed without refocusing. These economical lenses are available in working distances ranging from 35mm to 175mm and offer a maximum 2/3” sensor format. Iris versions (i-series) all have locking iris, front filter thread, removable mounting flange, and optional zoom lock. All lenses have a 50mm diameter flange (removable on iris versions except 450i Right Angle) for mounting. VZM™ Zoom Imaging Lenses are ideal for inspection of integrated circuits and solder joints. Also suited for quality control and laboratory inspection needs, as well as surface analysis.
Motorized lenses comes complete with encased DC Gear-motor with rubber o-ring belt drive and bracket, CE analog/RS-232 control unit, 10 ft. motor/controller cable, basic LabVIEW™ operation interface software disk (Windows® 98, 2000, or XP compatible), RS-232 cable, and CE universal power supply (110V & 220V operation) with removable US standard IEC power cord. The control unit allows the user to vary the zoom as well as the speed and direction at which zooming occurs. The controller has a manual mode for separate speed and direction or can be switched to RS-232 Mode with the RS-232 LabVIEW™ Program or with HyperTerminal. Dynamic braking is applied to motors for precise stopping. Up to two lenses can be driven by same controller, but not simultaneously. Controller has no position feedback or home position inputs; it is designed to be used with a vision system that provides motion control to a static image scenario. Controller is 3" H x 7" W x 5" D and weighs 2 lbs.
