The Kowa LM35EC-IR is a 35mm fixed focal length lens optimized for high-resolution surveillance and traffic imaging systems requiring compatibility with 1.2" format (19.2mm dia.) sensors and resolutions up to 24 megapixels. Designed to capture sharp imagery across the visible to near-infrared spectrum (400–1000nm), this IR-corrected C-Mount lens maintains consistent focus and clarity under variable lighting conditions—day or night.
Featuring manual focus, support for 2.5µm pixel sensors, and multiple interchangeable fixed apertures (F2.4 to F8), the LM35EC-IR is ideal for license plate recognition (LPR/ANPR), intelligent traffic systems (ITS), mapping, and high-precision machine vision. With a field of view at minimum focus distance of 222mm × 165mm, low TV distortion (-0.30%), and 200 lp/mm center resolution, this compact lens (Ø33 x 50.4mm, 80g) ensures dependable optical performance even in outdoor installations operating between -10°C and +50°C.
