The Kowa LM16EC-IR delivers exceptional optical performance for high-resolution imaging systems in demanding security, surveillance, and industrial environments. This 16mm fixed focal length lens supports large 1.2" sensors with up to 24 megapixel resolution and 2.5µm pixel pitch, offering ultra-sharp image capture across the full sensor area. Designed for C-Mount systems, it achieves 200 lp/mm resolution in the center and 125 lp/mm at the edges, with virtually no distortion (-0.60%). The manual focus design and 0.5m to ∞ focus range make it highly adaptable for precision imaging tasks.
Built with IR-corrected optics for 400nm–1,000nm wavelength coverage, this lens enables accurate imaging in both visible and near-infrared spectrums — ideal for 24/7 surveillance, traffic monitoring, and license plate recognition. With fixed aperture options (f/2.4 to f/8) via interchangeable plates, the LM16EC-IR allows flexible control over depth of field. Its compact Ø36 x 64.3mm form factor, 95g weight, and -10°C to +50°C operating range ensure reliable integration into rugged security and machine vision platforms.
