DM Optical 4/3″ 20MP FA Lens Series
The DM Optical FA Lens Series is purpose-built for high-resolution machine vision applications requiring precision and reliability. Designed to cover 4/3″ sensors with support for up to 20 megapixels, these C-Mount lenses deliver exceptional image quality across a range of focal lengths from 12mm to 50mm. Each lens features a broad aperture range of F2.8–22, enabling flexible exposure control in varied industrial lighting conditions. With low distortion figures as tight as <0.04% on the 35mm variant and compact minimum object distances starting from 0.1m, the series is ideal for inspection, measurement, and quality control tasks. Filter thread compatibility (M35.5×P0.5) is standard across most models, and the robust construction ensures consistent performance in demanding FA environments.
