Continuous Zoom Lens 0.7X–4.5X | C-Mount Industrial Camera Lens

LZ Series Continuous Zoom Lens for Industrial Cameras

The POMEAS LZ Series Continuous Zoom Lens is designed for industrial camera systems that require flexible magnification, stable image quality, and precise optical performance. With a 0.7X–4.5X zoom range, 87 ± 2 mm working distance, and C-Mount interface, this lens provides a reliable optical solution for machine vision inspection, precision measurement, and automated visual inspection systems.

Its continuous zoom structure allows users to adjust magnification smoothly while maintaining stable imaging performance. This makes it suitable for applications where different object sizes, inspection areas, or detail levels need to be observed within one optical system.

0.7X–4.5X Continuous Zoom Range

The LZ Series lens supports a 0.7X–4.5X zoom range, allowing users to switch from large field-of-view observation to detailed inspection without frequently replacing lenses. This helps reduce system adjustment time and improves flexibility for machine vision applications.

For production lines with multiple product sizes or variable inspection requirements, the continuous zoom design allows engineers to quickly adapt the imaging system to different tasks.

87 ± 2 mm Working Distance

With an 87 ± 2 mm working distance, this lens provides enough space for lighting, fixtures, and mechanical structures around the inspection target. It is suitable for industrial camera setups where both optical performance and installation space must be considered.

This working distance is especially useful for automated inspection equipment, visual positioning systems, and precision measurement stations.

Best Resolution 3.95 μm

The lens offers a best resolution of 3.95 μm, supporting clear image capture for small components, fine details, edges, and surface features. It helps machine vision systems obtain reliable image information for inspection, measurement, alignment, and defect detection.

This makes the lens suitable for high-precision industrial applications such as electronics inspection, semiconductor-related inspection, connector inspection, and precision component analysis.

Max NA 0.085 for Reliable Imaging

The LZ Series lens features a maximum NA value of 0.085, helping improve light collection and image clarity under suitable illumination conditions. For machine vision systems, stable optical performance is important for maintaining consistent inspection results.

When used with proper lighting and camera selection, the lens can support clear and repeatable imaging in industrial inspection environments.

Ultra-Low Distortion ≤ 0.001%

The lens provides ultra-low distortion of ≤ 0.001%, helping reduce image deformation during inspection and measurement. This is especially important for applications that require accurate edge recognition, dimensional measurement, position detection, and visual alignment.

Low distortion helps improve measurement reliability and reduces the difficulty of image correction during system integration.

Linear Field of View Change with Magnification

The field of view changes linearly with magnification, making system adjustment more predictable during continuous zoom operation. This helps engineers set up inspection parameters more efficiently and improves usability in machine vision applications.

For automated equipment and multi-product inspection systems, predictable field-of-view adjustment can help simplify debugging and improve production flexibility.

Compatible with Multiple Industrial Camera Sensors

The LZ Series Continuous Zoom Lens supports 1/3", 1/2", and 1" industrial camera sensors, making it suitable for different camera configurations and machine vision platforms. Its C-Mount design allows easy integration with many industrial cameras commonly used in automation and inspection systems.

This compatibility gives system integrators more flexibility when selecting cameras for different field-of-view, resolution, and inspection requirements.

C-Mount Design for Easy Integration

The standard C-Mount interface makes the lens easy to connect with industrial cameras, machine vision modules, inspection equipment, and customized optical systems. C-Mount lenses are widely used in machine vision cameras and industrial imaging systems, which makes integration more convenient for engineers and equipment manufacturers.

The compact lens structure also helps reduce installation difficulty in space-limited automation equipment.

Typical Applications

The POMEAS LZ Series Continuous Zoom Lens can be used in electronics inspection, PCB inspection, connector inspection, semiconductor component inspection, precision parts measurement, surface defect detection, visual positioning, automated quality control, industrial camera imaging, and machine vision system integration.

It is suitable for applications where users need adjustable magnification, low distortion, stable imaging, and flexible camera compatibility.
