A multichannel color measurement instrument for measuring spectral properties of a target comprises pick-up optics to collect measurement light, first and second anamorphic optical paths optically coupled to the pick up optics, a pick-up polarizing element located to polarize measurement light in the second anamorphic optical path, a reference anamorphic optical path including a reference illumination source, and a two-dimensional variable filter sensor having an optically transmissive filter function that varies in a first direction parallel to a surface of the variable filter sensor and is substantially constant in a second direction parallel to a surface of the variable filter sensor and orthogonal to the first direction. The anamorphic optical paths spread the measurement light in the first direction direct it on to different portions of the variable filter sensor.
