DM Optical FA Lens Series — 1/1.7″ 12MP

The DM Optical 1/1.7″ 12MP FA Lens Series is a versatile range of C-mount fixed focal length lenses designed for machine vision and factory automation applications. Available in focal lengths from 4mm to 75mm, the series is optimized for cameras with 1.85μm pixel size and supports resolutions up to 12MP, with full compatibility with the Sony IMX226 sensor.

The series is notable for its ultra-compact form factor, making it well suited for space-constrained inspection setups. Longer focal lengths (16mm and above) achieve distortion as low as <0.1%, while the 75mm model delivers an exceptionally low <0.058% — ideal for precision measurement tasks. The wide focal length range, combined with superior imaging performance, makes this series adaptable to a broad variety of fields of view, from wide-angle (86.1°×70.8° at 4mm) to narrow telephoto (5.1°×3.9° at 75mm).
