The Kowa LM50-IR-P is a 50mm fixed focal length lens with P-Mount (M42x1) threading, designed for large-format sensors up to 43.3mm. Its precision-engineered IR-corrected optics ensure stable focus across the visible to near-infrared spectrum (400–1000nm), making it ideal for demanding line scan systems and area sensor configurations.
This lens is built for industrial durability, featuring a robust metal housing with lockable iris and focus rings to maintain optical alignment in vibration-prone environments. The LM50-IR-P is engineered for advanced imaging platforms where accurate capture from daylight through NIR wavelengths is essential—such as in inspection, sorting, security, and multispectral applications.
