Kowa LM5NS40 | 1/1.8" 5mm Fixed S-Mount Lens, 2MP, 2.5µm Pixel, Manual Focus, Automotive & UAV, Visible (400–800nm)

The Kowa LM5NS40 is a high-precision fixed focal length S-Mount lens optimized for 1/1.8" format 2MP sensors with 2.5µm pixel pitch. Designed to deliver superior optical performance, it features a 5mm focal length paired with a fixed F4 aperture, providing excellent sharpness and contrast. The lens supports manual focus from 0.1 meters to infinity, enabling precise control in applications requiring accurate depth of field adjustments. With a center resolution of 200 line pairs per millimeter (lp/mm) and 100 lp/mm at the image margins, the LM5NS40 ensures crisp image quality for demanding machine vision, automotive, and UAV imaging tasks.

Engineered for challenging environments, this lens covers a wide visible wavelength range from 400 to 800nm, ideal for color and monochrome sensors. Its compact size (Ø21.5 x 29.9 mm) and lightweight 12g design make it well-suited for embedded systems with strict space and weight constraints. The lens maintains low distortion at -0.51% TV distortion, preserving geometric fidelity across the field of view (72.4mm horizontal and 57.0mm vertical at minimum working distance). Operating reliably in temperatures from -10°C to +50°C, the LM5NS40 is customizable with options for modified F-stops, IR cut filters, and shock-resistant glued elements to meet specialized application requirements.
