PMS-LZL-12105 12.5X Motorized Coaxial Zoom Lens for Machine Vision
The POMEAS PMS-LZL-12105 is a 12.5X motorized coaxial continuous zoom lens designed for machine vision inspection, semiconductor automation, electronics inspection and automated optical inspection applications. With an optical magnification range of 0.58X–7.5X and a 12.5:1 zoom ratio, the lens allows machine vision systems to switch between larger field-of-view observation and high-magnification detail inspection without frequently changing lenses.
The PMS-LZL-12105 supports industrial cameras with sensor formats up to 2/3 inch and uses a standard C-Mount interface. Its 77.4 ± 2 mm working distance provides practical installation space for lighting, fixtures and inspected parts.
The integrated coaxial optical path is particularly useful for relatively flat and reflective targets such as PCB pads, semiconductor components, connectors, printed markings and polished metal surfaces. Motorized zoom adjustment allows magnification to be controlled by the inspection system, making the lens suitable for automated equipment and multi-step vision processes.

Key Features
12.5X Continuous Zoom Ratio
The 12.5:1 zoom ratio provides a wide optical adjustment range, allowing one imaging system to handle different object sizes, inspection areas and feature dimensions.
0.58X–7.5X Optical Magnification
The wide optical magnification range supports both larger-area observation and high-magnification detail inspection within the same optical platform.
Motorized Zoom Control
Motorized zoom adjustment allows magnification to be changed through the inspection equipment, reducing manual intervention in automated machine vision systems.
Integrated Coaxial Illumination
The coaxial optical path provides on-axis illumination for relatively flat and reflective surfaces, helping improve visibility of surface details and reduce unwanted shadows.
77.4 ± 2 mm Working Distance
The specified working distance provides practical installation space for samples, lighting and fixtures while maintaining a stable mechanical setup.
Supports Up to 2/3-Inch Sensors
The optical system supports industrial cameras with sensor formats up to 2/3 inch and can also be used with smaller sensor formats.
C-Mount Camera Interface
The standard C-Mount interface supports convenient integration with commonly used industrial area-scan cameras.
Telecentric Optical Path
The optical design incorporates a telecentric optical path intended to improve imaging stability within this zoom-lens configuration. For high-accuracy dimensional measurement requiring strict object-side or bi-telecentric performance, a dedicated telecentric lens should be evaluated separately.
For a wider maximum field of view, compare the LZ-650104 6.5X motorized zoom lens.

Coaxial Illumination for Reflective Surfaces
Coaxial illumination directs light along or close to the imaging axis, making it particularly suitable for relatively flat and reflective inspection targets.
Typical targets include PCB pads, semiconductor packages, printed characters, connectors, polished metal surfaces and precision electronic components. The final illumination configuration should always be confirmed according to the material, surface reflectivity, defect type and required image contrast.
Field of View and Magnification Selection
The actual field of view depends primarily on the camera sensor size and selected optical magnification. Lower magnification provides a larger inspection area, while higher magnification provides a smaller field of view for detailed observation.
| Selection Item | Reference | Why It Matters |
|---|---|---|
| Camera Sensor Size | Up to 2/3 Inch | Affects the available imaging area and final field of view. |
| Optical Magnification | 0.58X–7.5X | Lower magnification provides a wider view; higher magnification provides finer detail. |
| Working Distance | 77.4 ± 2 mm | Determines the required installation space between the lens and inspected object. |
| Camera Interface | C-Mount | Supports integration with compatible industrial machine vision cameras. |
| Illumination | Coaxial | Useful for relatively flat and reflective inspection surfaces. |
Selection Note: For accurate field-of-view and resolution evaluation, please provide the camera model or sensor dimensions, pixel size, object dimensions, required field of view, working distance, smallest inspection feature and required inspection accuracy.
Motorized Zoom for Automated Inspection
Motorized zoom allows the PMS-LZL-12105 to change optical magnification through the machine vision system rather than requiring manual lens adjustment.
This is useful for automated inspection equipment that needs to inspect different product sizes, switch between positioning and detailed inspection, or use multiple magnification settings during different inspection steps.
The exact motor controller, cable, communication interface and software integration should be confirmed according to the final equipment configuration before ordering.
Typical Applications
Semiconductor Inspection
Suitable for semiconductor packages, bonding areas and reflective microstructures where adjustable magnification and coaxial illumination are useful.
PCB Inspection
Coaxial illumination can improve visibility of PCB pads, printed markings, solder-related features and other relatively flat reflective areas.
Electronic Component Inspection
The wide zoom range supports observation of connectors, terminals, communication components and other small electronic parts.
Reflective Surface Inspection
On-axis illumination is useful for polished metal, flat reflective surfaces and other targets where conventional directional lighting may create strong shadows or glare.
Automated Optical Inspection
Motorized zoom allows automated systems to switch between different fields of view during different inspection steps.
Machine Vision R&D
The 12.5X zoom range is also useful for machine vision development, optical evaluation and laboratory imaging platforms.
Camera and System Integration
The PMS-LZL-12105 uses a standard C-Mount interface and supports industrial cameras with sensor formats up to 2/3 inch.
