Kowa LM5NS28 | 1/1.8" 5mm Fixed S-Mount Lens, 2MP, 2.5µm Pixel, 72.4° HFOV, Manual Focus, Visible (400–800nm)
The Kowa LM5NS28 is a high-performance fixed focal length lens designed for 1/1.8" image sensors, delivering 2MP resolution with a 2.5µm pixel size optimized for sharp, detailed imaging. It features a 5.0mm focal length with a wide 72.4° horizontal field of view (HFOV) and an F/2.8 fixed aperture, providing excellent light transmission and clarity. The lens supports manual focus adjustment from 0.1 meters to infinity, making it ideal for precision imaging in automotive, UAV, and drone applications requiring reliable visual capture across various distances and lighting conditions.
Engineered for visible spectrum use (400–800nm), the LM5NS28 lens achieves a center resolution of 200 line pairs per millimeter (lp/mm) and 100 lp/mm at the edges, ensuring sharpness across the frame. Its compact size (Ø21.5 x 29.9mm) and lightweight 12g construction allow seamless integration into space-constrained optical systems. The lens offers an M12 x 0.5 filter thread for added customization, and optional enhancements include modified F-stops, IR cut filters, shock-resistant glued elements, or a complete custom optical/mechanical redesign tailored to specific industrial requirements.
