PMS-LZH-7504 4K Continuous Zoom Lens for Machine Vision

The POMEAS PMS-LZH-7504 is a 4K continuous zoom lens designed for machine vision, semiconductor inspection, electronics inspection and automated optical inspection. Its 0.68X–5.0X optical magnification range allows one imaging system to move efficiently between larger field-of-view observation and high-magnification detail inspection.

The optical system supports industrial cameras with sensor formats up to 1 inch, uses a standard C-Mount interface and provides an 80 mm working distance. With a compatible 1-inch industrial camera, the optical platform is designed to support horizontal image resolution at the 4K level.

Compared with conventional zoom optics at the same magnification, the large-format optical design can provide a field of view approximately 1.45X larger, helping machine vision systems inspect a larger area without sacrificing high-magnification detail capability.

The PMS-LZH-7504 uses a streamlined non-coaxial configuration, making it suitable for systems using external ring lights, bar lights, backlights or other machine vision illumination.

Key Features

0.68X–5.0X Continuous Zoom

The wide optical magnification range allows one imaging system to cover both large-area observation and detailed local inspection without frequently replacing lenses.

4K-Level Optical Resolution

The optical system is designed for high-resolution industrial imaging. When paired with a suitable 1-inch camera, horizontal image resolution can reach the 4K level.

Supports Up to 1-Inch Sensors

The large-format optical design supports industrial cameras with sensor formats up to 1 inch, providing a wider field of view than traditional smaller-format zoom systems.

Approximately 1.45X Larger FOV

With a 1-inch camera, the optical platform can provide approximately 1.45X the field of view of conventional zoom optics at the same magnification, depending on the comparison configuration.

TV Distortion Below 0.02%

Low TV distortion across the documented magnification range helps maintain stable image geometry for machine vision inspection.

80 mm Working Distance

The 80 mm working distance provides practical clearance for inspected parts, fixtures and external machine vision illumination.

Motorized Zoom Adjustment

Motorized magnification adjustment supports automated inspection equipment that requires remote zoom control or multiple optical settings.

Modular Optical Platform

Compatible TV tubes, auxiliary lenses and optical accessories can be selected according to the required camera format, field of view and inspection configuration.

Large Field of View with 1-Inch Cameras

One of the main advantages of the PMS-LZH-7504 optical platform is its compatibility with industrial cameras using sensor formats up to 1 inch.

Compared with conventional zoom systems using smaller image formats, the larger supported sensor allows a wider object area to be captured at the same optical magnification. POMEAS documentation specifies an improvement of approximately 1.45X in field of view when using the corresponding 1-inch camera configuration.

A larger field of view can reduce the need for mechanical camera movement or multiple image acquisitions when inspecting larger parts. Actual field of view should be calculated using the effective dimensions of the selected camera sensor and optical magnification.

Motorized Zoom for Automated Inspection

The PMS-LZH-7504 is intended for automated machine vision systems requiring electronically controlled magnification adjustment. Motorized zoom allows the inspection system to switch between different optical magnifications without manual lens adjustment.

This is useful for production equipment that handles multiple product sizes, uses different inspection fields during different process steps, or requires remote optical configuration.

The exact motor controller, communication interface, cable and software protocol should be confirmed according to the final system configuration before ordering.

External Illumination and Straight-Barrel Integration

The PMS-LZH-7504 uses a non-coaxial configuration without an integrated coaxial illumination side port. This makes the lens suitable for machine vision systems using external lighting configurations such as ring lights, bar lights, backlights and other dedicated illumination.

The streamlined lens structure can simplify installation in machine vision equipment where the optical axis, camera and external lighting need to be arranged within limited mechanical space.

If integrated coaxial illumination is required for reflective or flat surfaces, a corresponding coaxial 4K zoom-lens configuration should be selected instead.

Frequently Asked Questions

What is the magnification range of the PMS-LZH-7504?

The optical magnification range is 0.68X to 5.0X. The previously published 0.58X value should not be used for this 4K optical platform.

What camera sensor size does the lens support?

The PMS-LZH-7504 supports industrial cameras with sensor formats up to 1 inch.

What is the working distance?

The specified working distance is approximately 80 mm.

Is the PMS-LZH-7504 motorized?

Yes. This configuration uses motorized zoom adjustment for integration into automated inspection equipment. Controller and communication options should be confirmed according to the final system configuration.

Does this model include coaxial illumination?

This configuration uses a non-coaxial optical structure and is intended for use with external illumination. If integrated coaxial illumination is required, a coaxial 4K zoom-lens configuration should be selected.

How much larger is the field of view?

POMEAS documentation specifies approximately 1.45X the field of view of a conventional comparison system at the same magnification. This corresponds to approximately a 45% increase, not a 145% increase.

Does the lens support 4K imaging?

Yes. The optical system is designed so that, when paired with a suitable 1-inch industrial camera, horizontal image resolution can reach the 4K level.
