A method for registering a color filter array to a back illuminated imager is disclosed, comprising the steps of providing at least one color filter array comprising filter elements of at least a first color and a second color; providing at least one back illuminated imager having a front side and a back side and comprising a plurality of pixels proximal to the front side, a first portion of the plurality of pixels being associated with the first color, and a second portion of the plurality of pixels being associated with the second color; illuminating the at least one color filter array and the back side of the back illuminated imager with monochromatic light having a wavelength corresponding to the first color; rotating and translating the at least one color filter array relative to the back illuminated imager; measuring a first response of at least one pixel associated with the second color; and repeating the rotating, translating, and measurement steps until the response is a minimum. The aligned back illuminated imager can then be adhered to the color filter array by means of an adhesive.
