Kowa LM3JC10M | 2/3" 3.7mm Fixed Lens, 10MP, C-Mount, 2.4µm Pixel, Visible to NIR (400–1000nm)
The Kowa LM3JC10M is a 3.7mm fixed focal length C-mount lens engineered for 2/3" format sensors with high-resolution support up to 10 megapixels and pixel sizes down to 2.4µm. Designed for compatibility with sensors such as the Sony IMX250, IMX264, and Aptina MT9D131, the LM3JC10M ensures precision imaging with excellent contrast and clarity. Its high-resolution optics deliver 200 lp/mm at the center and 125 lp/mm at the image edge, supporting detailed image capture even in demanding industrial or machine vision environments. A wide field of view at minimum working distance (278.7mm horizontal, 207.3mm vertical) enables large-area coverage for close-range inspection.
This lens features a manual iris (f/2.8 to f/16) and a floating focus mechanism to minimize aberrations across the entire 0.1m to infinity range. Its broadband coating enables transmission across the 400nm–1000nm wavelength range, covering visible to near-infrared (VIS-NIR) applications. Built for performance and durability, the lens maintains optical stability from -10°C to +50°C operating temperatures. The LM3JC10M’s low distortion (-0.09% TV) and compact Ø57 x 54mm housing make it a reliable choice for systems that demand precision imaging, including automated inspection, robotics, and intelligent traffic systems.
