ID-3729 ABSTRACT OF THE DISCLOSURE A novel solid state array detector is useful in an optical spectrometer of the type that includes a crossed dispersion system receptive of radiation for producing a pair of two dimensional displays of spectral lines characteristic of at least one atomic element. One display is ultraviolet and the other is visible. A solid-state chip has on the front surface a two dimensional array of photosensitive pixels receptive of radiation of selected spectral lines and proximate background radiation. The pixels are arranged in a plurality of sub-arrays with each sub-array consisting of at least one of the pixels and are positioned at a projection location on the front surface of at least one of the selected spectral lines. Electronic components formed on the chip among the sub-arrays are operatively connected to the pixels for producing readout signals correlating with intensities of the selected spectral lines.
