A method and system for providing different images representing plural depths
of
field of an electronic device. The vision system has a beamsplitter for receiving
an image of the device illuminated by the at least one light source, the beamsplitter
providing one of the plurality of images of the device based in a wavelength of
the light source; an aperture having a plurality of effective diameters based on
the wavelength of light from the at least one light source, the aperture determining
a depth of field of the image of the device; and an optical element for receiving
the image of the device, the optical element magnifying the image by a predetermined
magnification factor to produce a magnified image having the determined depth of field.
