Industrial Applications

1. Precision inspection of moderate working-distance parts

The 35mm focal length and 2/3-inch image circle suit inspection stations that need a tighter field of view than standard 25mm lenses while keeping stable C-mount integration.

Problem Solved

Reduces perspective distortion and improves defect visibility on small components at fixed standoff distances.

2. Barcode and label reading on constrained conveyor lanes

The manual focus range from 0.3 m to infinity and F1.4 aperture support installation in narrow conveyor cells where lens position must be locked after commissioning.

Problem Solved

Maintains focus and image brightness in compact reading stations with limited mounting adjustment.

3. Gauge and metrology imaging on industrial benches

The lens’s low distortion specification and fixed-mechanics design make it suitable for measurement setups requiring repeatable imaging geometry.

Problem Solved

Improves measurement consistency by limiting image warping and preventing ring drift after alignment.
