Abstract
A method and system for providing different magnified images of an electronic device. The vision system has a first beamsplitter for receiving an image of the device illuminated by a light source, the beamsplitter providing multiple of images of the device; optical elements for receiving the plural images of the device, each of the optical elements magnifying the image by a predetermined magnification factor to produce more than one magnified images; and a second beamsplitter for receiving the magnified images and filtering out all but one of the magnified images based on a wavelength of the light source.
