Kowa LM50-IR-F | 43.3mm Format 50mm IR-Corrected Fixed Lens, F-Mount, Visible to NIR (400–1000nm), Manual Iris/Focus, -0.54% Distortion

The Kowa LM50-IR-F is a precision-engineered 50mm fixed focal length lens built for high-resolution large format imaging up to 43.3mm sensor diameters. Designed with F-mount compatibility, this IR-corrected lens supports sharp, chromatic-aberration-free imaging from visible to near-infrared (400–1000nm) wavelengths. With a bright f/1.9 aperture and manual iris control, it delivers optimal light throughput and depth of field control in demanding machine vision, inspection, and line scan applications.

Engineered for reliability in industrial environments, the LM50-IR-F features robust metal housing, manual focus with a 0.5m minimum object distance, and low TV distortion of just -0.54%. Its M52 filter thread, large 117.5mm housing length, and 600g weight provide durable system integration. Operating from -10°C to +50°C, this lens is ideal for multi-spectral inspection, document scanning, metrology, and high-speed line scan use cases requiring wide sensor coverage and consistent optical accuracy.
