Kowa LM50-IR-F F1.9 50mm Lens is a large format, IR corrected lens with broadband coating and low distortion. The LM50-IR maintains its superior performance from visible to near infrared wavelengths (NIR) without any focus shift. In addition, Kowa now offers the LM50-IR-P lens which provides all of the same outstanding capabilities as the LM50-IR, but with M42-mount capabilities.

Suitable for solar panel inspection, ITS, visible/NIR line scan, and large format area scan applications. This lens has a fixed focal length of 50mm and an aperture range of f/1.9 to 16.0.

The lens is exceptionally clean, aperture works smoothly.
