IDS 25mm C-Mount Lens – Model Ma-12M120-C2528 (1.2″, 12MP, F2.8–F16)

The IDS Ma-12M120-C2528 is a high-precision 25mm C-Mount lens engineered for modern industrial imaging systems requiring outstanding sharpness and stability. Optimized for large 1.2″ sensors and supporting resolutions down to 3.45 μm pixel pitch, this macro-capable 12MP lens delivers exceptional contrast, minimal distortion, and consistent performance across short and mid-range working distances. Its manual iris and focus rings allow fine optical tuning, making it suitable for machine vision inspection, electronics quality control, and metrology applications where accuracy and repeatability matter.
