Fixed-focus camera objective CF-HA

inspectionautomated optical inspectionmachine vision

Overview
FUJINON CF-HA Series machine vision lenses are compatible with large 1-inch image sensors and support up to 1.5 megapixel resolution (7.4 μm pixel pitch). The line includes fixed focal lengths 12.5, 16, 25, 35, 50 and 75 mm with C-mount and M49 x 0.75 filter thread.

Main features

• Low TV distortion: minimized distortion for high-accuracy applications such as dimensional measurement and automated inspection.
• High close-up performance: rear-focusing method on CF12.5HA-1 and CF16HA-1 improves imaging at short working distances.
• Low F-number: available down to F1.4 on most models for improved low-light capture; CF50HA-1 and CF75HA-1 start at F1.8.
• Good peripheral illumination: maintains sufficient light at image edges to support stable inspection accuracy.
