Motorized Zoom for Automated Inspection

The LZG-63105-A uses motorized magnification adjustment, making it suitable for machine vision systems that need to switch between different fields of view without manually adjusting the lens.

Typical applications include multi-product inspection, automated optical inspection, remote optical adjustment and systems that require different magnification settings during different inspection steps.

The controller, cable and electrical interface should be selected according to the final system configuration. Confirm the required control method and integration interface before ordering.

Camera and Lens Selection

The C-Mount interface and support for sensors up to 2/3 inch allow the LZG-63105-A to be integrated with a wide range of industrial area-scan cameras.

Browse POMEAS industrial machine vision cameras for compatible camera options.

Camera sensor size, pixel size, resolution, required field of view, working distance and smallest inspection feature should be evaluated together rather than selecting a lens based only on magnification.

For additional guidance, read the POMEAS continuous zoom lens selection guide to learn how camera specifications, field of view, working distance, inspection requirements and zoom control affect lens selection.
