A system for generating focused color image data of an object, the system comprising: a polychromatic light source that produces light comprising a first wavelength, a second wavelength, and a third wavelength; an optics system optically coupled to the polychromatic light source and operable to focus each of the first, second, and third wavelengths to a corresponding plurality of respective focal lengths; a detector configured to collect intensity data for each of the first, second, and third wavelengths at each corresponding plurality of respective focal lengths, the detector comprising first pixels sensitive to the first wavelength, second pixels sensitive to the second wavelength, and third pixels sensitive to the third wavelength; and a processor configured to, for a location in the intensity data: determine, for each of the first, second, and third wavelengths, a focal length for which the respective wavelength is focused relative to an object at the location in the intensity data; and combine the intensity data for each of the first, second, and third wavelengths at the determined focal length, thereby generating focused color image data for the location in the color intensity data.
