6.5X Zoom Lens with 3mm Fine Focus | 0.7X–4.5X, 2/3", WD 87mm

The LZ-63102-M3 is a 6.5X industrial zoom lens designed for machine vision inspection, precision imaging and optical measurement applications. With a 6.5:1 zoom ratio and 0.7X–4.5X magnification range, it gives engineers the flexibility to switch from a wider field of view to higher magnification without changing the lens setup.

This model supports camera sensors up to 2/3" and offers a working distance of 87±2mm, making it suitable for compact inspection systems where both image clarity and installation space matter. Its built-in 3mm fine focus adjustment helps operators achieve clear focus on workpieces with small height differences, while keeping the original working distance stable.

Key Features

6.5:1 Continuous Zoom Range

The LZ-63102-M3 covers 0.7X to 4.5X magnification, giving users a practical zoom range for different inspection tasks. It is suitable for applications that require both wide-area observation and detailed image capture.

Built-in 3mm Fine Focus Adjustment

The integrated fine-tuning mechanism provides a 0–3mm focus adjustment range. This is especially useful when inspecting parts with slight height variations or when the lens is installed in a limited working space.

Designed for 2/3" Industrial Cameras

With support for sensors up to 2/3", this lens helps achieve a larger field of view while maintaining stable image performance for machine vision systems.

87±2mm Working Distance

The 87±2mm working distance provides a practical balance between installation flexibility and optical performance, making the lens easy to integrate into automated inspection equipment.
