Kowa LM25RW | 1/1.8" 25mm Fixed Lens, F3, S-Mount, Lock-Ring Focus, 0.2m–∞

Engineered for 1/1.8" sensor formats, the Kowa LM25RW is a 25mm fixed focal length lens with an F3 fixed aperture optimized for consistent light transmission and stable exposure in machine vision applications. The lock-ring focus mechanism enables precise set-and-forget focusing from 0.2 m to infinity, maintaining sharpness under vibration or repeat-duty cycles common on inspection lines and robotic cells. Its S-mount design provides compact integration for embedded and small-form-factor cameras.

The LM25RW’s 25mm focal length provides a versatile working distance for compact cells and benchtop stations, supporting crisp detail capture on typical 1/1.8" sensors used across AOI, metrology, packaging, and code reading. Fixed aperture simplifies repeatability, while the mechanical build supports reliable alignment and long service life. This lens is ideal for high-stability imaging pipelines where precise focus lock and mechanical reliability are critical.
