Abstract: A system for imaging an object is described. The system includes a light source (200) for illuminating the object (210) with light, the light from the light source (200) having a first wavelength. The system further includes an image capturing device (240) and a filter device (220). The filter device (220) is transmissive for light having a wavelength which is different than the first wavelength, and reflective for light having the first wavelength, the image capturing device (240) capturing an image of at least a portion of the object (210) using light transmitted through the filter device (220). The system may further include a dark field illumination system (400) for illuminating the object (210) either simultaneously with the illumination by the first light source (200), or sequentially with respect to the illumination by the first light source (200).
