The XC-series is for sensor sizes up to 23mm image circle.
The resolution of this C-mount lens series is 160lp/mm in the center and thus matches perfectly with sensors such as the ON Semi KAI-08050 or CMOSIS CMV8000.
Just as other machine vision lenses from Kowa this series is constructed to withstand high requirements on vibration, shock and temperature.
All models are equipped with a special broadband coating for extraordinary Transmission wavelength at NIR wave length.
