A color measuring sensor assembly includes an optical filter such as a linear variable filter, and an optical detector array positioned directly opposite from the optical filter a predetermined distance. A plurality of lenses, such as gradient index rods or microlens arrays, are disposed between the optical filter and the detector array such that light beams propagating through the lenses from the optical filter to the detector array project an upright, noninverted image of the optical filter onto a photosensitive surface of the detector array. The color measuring sensor assembly can be incorporated with other standard components into a spectrometer device such as a portable colorimeter having a compact and rugged construction suitable for use in the field.
