The illumination is very critical factor in machine vision system with optical lens, also image information changes depending on the illumination condition and applications.
Finally, it will be not only effect the measurement value of improper illumination selection but irritated uncorrected data thus we have to choose proper intensity of illumination according to the F/#, sensitivity of camera, setting value(gain, shutter speed).
LED illumination is more long life and low consumption than halogen lamp in the machine vision application.
Therefore, it has been applied of various applications due to wide range of divergence, various color, compact shape and it is possible to corrected measure regarding of certain wavelength.
SPO will provide you to get the proper condition in the system also LED controller to control the illumination.
