In the field of industrial automation and quality inspection, industrial zoom lens is an indispensable machine vision device. It provides accurate imaging support for machine vision systems by flexibly adjusting the magnification, and is widely used in high-precision scenarios such as electronics inspection, semiconductor packaging, and biomedicine.

I. Zoom lens vs Fixed lens: What's the difference?

Traditional fixed lens focal length is fixed, need to replace the lens to achieve different magnification, the operation is cumbersome and high cost. The industrial zoom lens can realize stepless zoom without replacing the lens through the continuous movement of the internal optical group mirror, and the coverage of magnification is usually up to 0.7X-4.5X (with the extension lens can reach higher magnification), which significantly improves the inspection efficiency and flexibility.

II. Analysis of Core Technical Parameters

1. zoom range and resolution: the wider the zoom range, the more applicable scenes; high-resolution lenses (e.g., 5/12 megapixel class) can capture more subtle defects.

2. aberration control: low aberration design (<0.1%) ensures true image reproduction and avoids measurement errors.

3. working distance and depth of field: long working distance (e.g., more than 100mm) to adapt to complex mechanical structures, large depth of field to ensure the clear imaging of three-dimensional objects.

4. interface compatibility: support C/CS/F mount and other mainstream interfaces, seamless connection to industrial cameras.

III. Typical Application Scenarios

- Electronic manufacturing: detect PCB lines, chip pins false soldering;

- Precision machining: monitor metal parts burrs, cracks;

- Life sciences: observe cell culture, pill surface defects;

- Logistics sorting: identify bar codes, package integrity.
