Kowa LM25EC-IR | 1.2" 25mm IR-Corrected Fixed Lens, 24MP, C-Mount, 2.5µm Pixel, Visible to NIR (400–1000nm)

The Kowa LM25EC-IR is a high-performance 25 mm fixed focal length lens engineered for high-resolution machine vision, inspection, ITS/traffic systems, and NIR imaging applications. Designed for 1.2" sensors with a 19.2 mm image circle, this lens supports up to 24 megapixels and excels in applications requiring high pixel density with 2.5 µm pixel pitch. The lens delivers ultra-sharp detail across the frame, achieving 200 lp/mm at the center and 125 lp/mm at the margins, making it ideal for systems demanding edge-to-edge clarity and precision. Its IR-corrected optics ensure accurate focus across both visible and near-infrared spectra (400–1000 nm), enabling reliable performance in day/night and dual-sensor environments.

Built with manual focus control, a wide 0.5 m to ∞ focus range, and swappable fixed aperture plates (F2.4 to F8), the LM25EC-IR offers optical versatility across diverse lighting conditions and working distances. A generous field of view (315 mm horizontal, 233 mm vertical) at minimum working distance supports large-scene coverage without distortion (TV distortion -1.00%). With a standard C-Mount, compact housing (Ø36 x 67.2 mm), and light weight (90 g), this lens integrates easily into industrial setups. Operating across -10°C to +50°C, the LM25EC-IR excels in demanding imaging environments requiring high-speed frame rates and megapixel accuracy.
