Kowa LM50-IR-F 50mm IR-Corrected F-Mount Lens for 43.3mm Large Format Sensors Visible to NIR 400–1000nm Manual Iris and Focus Low Distortion

*Please note this product is subject to tariff fee*

The Kowa LM50-IR-F is a 50mm fixed focal length lens designed for large-format sensors up to 43.3mm in diameter. Its IR-corrected optics provide exceptional clarity from visible light through the near-infrared spectrum (400nm–1000nm), making it a powerful solution for dual-mode imaging. With a manual iris ranging from f/1.9 to f/16 and a robust F-mount, this lens is ideal for precision imaging in machine vision, automation, and industrial inspection systems.

Built for reliability in demanding environments, the LM50-IR-F includes manual focus control with a close range starting at 0.5 meters. It features a distortion rating of just -0.54%, M52 filter threading, and a large-format-friendly optical path. The durable construction weighs 600g and supports continuous operation in temperatures from -10°C to +50°C. This lens is purpose-built for line scan, area scan, and multispectral imaging platforms that demand accurate and consistent results.
