PMS-LZL-12100D15 12.5X Detented Continuous Zoom Lens

The PMS-LZL-12100D15 is a 12.5X manual detented continuous zoom lens designed for semiconductor inspection, industrial automation, electronics manufacturing, precision inspection and machine vision applications. It provides a wide optical magnification range from 0.58X to 7.5X.

Unlike a standard manual continuous zoom lens, this model features 15 mechanical detent positions. These predefined zoom positions help operators return to specific magnification settings with improved repeatability, making the lens suitable for standardized inspection processes, multi-product inspection and applications requiring repeatable optical configurations.

Why Use a Detented Zoom Lens?

A standard continuous zoom lens can be adjusted freely throughout its magnification range, but manually returning to exactly the same zoom position may introduce operator-dependent variation.

The PMS-LZL-12100D15 uses 15 predefined mechanical detent positions to help operators return to specific magnification settings more consistently. This makes it useful for standardized inspection procedures, repeated measurement tasks and production environments where multiple operators need to use the same optical settings.

For applications that do not require mechanical detent positions, view the PMS-LZL-12100 12.5X manual continuous zoom lens .

Typical Applications

Semiconductor inspection
PCB and electronic component inspection
Communication component inspection
Precision dimensional inspection
Surface defect inspection
Standardized multi-magnification inspection
Automated production equipment

Laboratory imaging and observation

Camera and System Integration

The PMS-LZL-12100D15 supports machine vision cameras with sensor formats up to 2/3 inch and uses a standard C-Mount interface.

Camera sensor size, pixel size, required field of view, working distance, smallest inspection feature and required inspection accuracy should be considered together when selecting the lens and camera combination.

Browse POMEAS industrial machine vision cameras for compatible camera options. Camera sensor size should not exceed the maximum image format supported by the lens.
