IDS 35mm C-Mount Lens – Model Ma-12M120-C3528 (1.2″, 12MP, F2.8–F16)

The IDS Ma-12M120-C3528 is a high-precision 35mm C-Mount industrial lens engineered for modern machine vision systems that demand exceptional optical stability, low distortion, and high image clarity. Designed for large 1.2-inch sensors and resolutions down to 3.45 μm pixel size, this 12MP-class macro lens delivers superb contrast and uniform sharpness across the field. Its manual iris and focus controls offer fine-tuned performance, while the extended working distance range of 47 to 185 mm supports inspection tasks requiring both close-range macro detail and mid-range imaging. Built with a robust housing and optimized chief ray angle, it ensures reliable operation even in demanding automation environments.
