Computar F1228-MPT 45 Megapixel 1.4" 12mm F2.8 (C Mount) Machine Vision Lens

The Computar F1228-MPT is a high-resolution 12mm fixed focal length lens engineered for next-generation machine vision systems requiring exceptional clarity, low distortion, and precise imaging performance. Designed to support up to 45 megapixel sensors and a large 1.4” optical format, this lens is ideal for advanced inspection, metrology, and automation environments where detail accuracy is critical.

Optimized for modern high-density sensors such as Sony IMX350 (2.74µm pixel size), the F1228-MPT delivers outstanding image sharpness across the entire field, minimizing edge degradation and maintaining consistent performance from center to corner. Its ultra-low distortion design ensures accurate measurement and reliable image processing results—essential for applications like dimensional inspection, robotics guidance, and precision alignment.

With a fast F2.8 aperture, this lens provides excellent light transmission for improved performance in controlled and low-light industrial environments. The manual iris control allows integrators to fine-tune depth of field and exposure settings based on application requirements. Built with a compact, lightweight housing, the F1228MPT is well-suited for space-constrained systems, including embedded vision platforms and multi-camera setups.

Fully compatible with C-mount camera systems, this lens integrates seamlessly into a wide range of machine vision cameras used in factory automation, quality inspection, logistics, and robotics.
