Kowa EC-IR 24 MP IR-Corrected Lenses
for visible-to-NIR imaging

Kowa EC-IR lenses are high-resolution, IR-corrected C-mount lenses designed for machine vision and imaging applications using large-format sensors up to 1.2". Supporting resolutions up to 24 megapixels and pixel sizes down to 2.5 µm, the EC-IR Series delivers high-resolution imaging with low distortion across the visible and near-infrared spectrum from 400 to 1000 nm.

The IR-corrected optical design minimizes focus shift between visible and near-infrared wavelengths to maintain sharp, high-contrast images when illumination changes between visible and NIR light. EC-IR industrial lenses are particularly well suited for traffic monitoring, automatic license plate recognition (ALPR), machine vision inspection, geo-mapping, and other applications requiring consistent imaging during changing lighting conditions. EC-IR lenses feature manual focus from 0.5 m to infinity and interchangeable fixed aperture plates. The combination of 1.2" sensor coverage, high resolution, IR correction, and multiple focal lengths provides system designers with flexible lens choices for high-performance visible/NIR imaging systems.
