The Kowa LM25EC-IR is a high-resolution 25mm fixed lens designed for professional surveillance, traffic monitoring, and machine vision systems that require superior image clarity and day/night reliability. Optimized for large 1.2" image sensors (19.2mm diagonal), it supports up to 24 megapixels and is built to handle pixel sizes as small as 2.5µm—perfect for today’s high-speed, high-detail industrial cameras. Its IR-corrected optics ensure accurate imaging across the 400–1000nm spectrum, allowing for crisp results in both visible and near-infrared light conditions.
With a manual focus range from 0.5 meters to infinity, low distortion (-1.00%), and a field of view of 315mm (H) x 233mm (V) at minimum working distance, this lens is ideal for traffic enforcement, license plate capture, ITS systems, and perimeter security. Interchangeable fixed apertures (F2.4 to F8) offer precise light control for consistent image quality across changing light environments. Housed in a compact Ø36 x 67.2mm body and weighing just 90g, the LM25EC-IR is easy to integrate with standard C-Mount cameras in tight or mobile configurations. Built to operate from -10°C to +50°C, it’s ready for reliable performance in real-world surveillance deployments.
