ABSTRACT:
Systems and methods for operating a vision system to provide a desired illumination wavelength for an inspection operation on workpiece include illuminating a workpiece using narrowband illumination from a continuously variable filter, and modifying the narrowband illumination and evaluating resulting images until a narrowband illumination is found that reliably supports the inspection operation. The initial narrowband illumination may be based on spectral sensing.
