Industrial Applications

1. Inline machine vision inspection cell

The 12.5-75 mm manual zoom and f/1.2 aperture let integrators frame variable part sizes while keeping exposure margins in controlled lighting.

Problem Solved

Eliminates the need to swap lenses when inspection stations must cover multiple field-of-view sizes on one camera.

2. Robotics workstation vision camera

The manual focus and iris with locking set screws help stabilize calibration after setup on fixed robotic inspection or guidance rigs.

Problem Solved

Prevents drift in focus and exposure after mechanical adjustment or vibration in a production robot cell.

3. Industrial security / monitoring at variable stand-off

The 6x zoom range supports wide-to-narrow framing changes for monitoring equipment, gates, or process areas without changing the camera body.

Problem Solved

Provides a single-lens solution when operators must alternate between overview and detail viewing distances.
