Key Features
14X Continuous Zoom Range
The PMS-LZH-14105K provides 0.55X–7.6X optical magnification, allowing the imaging system to move between large-area observation and high-magnification detail inspection without frequently changing lenses.
Large Field of View at Low Magnification
At 0.55X magnification, the lens provides a large observation area for object positioning, overview inspection, alignment and target location.
High-Resolution Imaging at High Magnification
At higher magnification, optical resolution reaches approximately 2.80 μm under the specified optical conditions, supporting detailed industrial imaging and small-feature observation.
Low TV Distortion
Low TV distortion helps maintain stable object geometry across the image and reduces the amount of software correction required for many industrial inspection applications.
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 1/2-inch and 1/3-inch camera sensors.
Manual or Motorized Configurations
Manual and motorized zoom configurations are available, allowing the optical system to be selected for laboratory observation, manual inspection or automated machine vision equipment.
Coaxial Illumination
Coaxial illumination directs light along the imaging axis and is useful for reflective or relatively flat surfaces such as PCB pads, semiconductor components and polished metal parts.
77.8 ± 2 mm Working Distance
The specified working distance provides practical space for illumination, samples and fixtures while supporting a relatively stable mechanical installation.

Coaxial Illumination for Reflective Surfaces
Coaxial illumination directs light along or close to the imaging axis, making it particularly useful for relatively flat and reflective inspection targets.
Typical targets include PCB pads, semiconductor packages, printed markings, polished metal surfaces, connectors and precision electronic components. The final lighting configuration should always be selected according to the material, surface reflectivity and defect type.
Manual and Motorized Zoom Configurations
The 14X zoom lens platform can be configured for manual or motorized magnification adjustment depending on the inspection system.
Manual adjustment is suitable for laboratory imaging, engineering evaluation and inspection stations where magnification is changed occasionally. Motorized configurations are more suitable for automated equipment, remote optical adjustment and machine vision systems that need to switch between different fields of view during the inspection process.
For motorized configurations, the controller, cable, electrical interface and communication requirements should be confirmed before ordering.
Typical Applications
The PMS-LZH-14105K is suitable for industrial imaging applications that require a wide magnification range, high optical resolution, low distortion and flexible field-of-view adjustment.
