Kowa LM5NS40 S-Mount 5mm Lens for 2MP 1/1.8" Sensors – Low Distortion, Manual Focus, 2.5µm Pixel, Visible 400–800nm

*Please note this product is subject to tariff fee*

The Kowa LM5NS40 is a precision-engineered S-Mount lens built for 1/1.8" image sensors with resolutions up to 2 megapixels and pixel sizes down to 2.5µm. With a fixed focal length of 5mm and a factory-set F4 aperture, this lens delivers sharp optical performance across the frame — reaching up to 200 lp/mm at center and 100 lp/mm at the edge. Manual focus control offers exact distance adjustment from 0.1 meters to infinity, making it a versatile choice for vision systems where accuracy and image clarity are key.

Designed to perform in compact, embedded platforms, the LM5NS40 supports high-resolution imaging across the 400–800nm visible spectrum. It is ideal for lightweight drone systems, embedded automotive vision, and compact machine vision cameras. The low -0.51% TV distortion ensures geometric fidelity, while the rugged housing, compact 21.5mm x 29.9mm dimensions, and 12g weight make it easy to integrate. Optional factory customization includes IR cut filters, fixed F-stop variations, and glued optics for vibration and impact resistance.
