Abstract
A system for imaging an object is described. The system includes a light source for illuminating the object with light, the light from the light source having a first wavelength. The system further includes an image capturing device and a filter device. The filter device is transmissive for light having a wavelength which different than the first wavelength, and reflective for light having the first wavelength, the image capturing device capturing an image of at least a portion of the object using light transmitted through the filter device. The system may further include a dark field illumination system for illuminating the object either simultaneously with the illumination by the first light source, or sequentially with respect to the illumination by the first light source.
