摘要: A spectrometer apparatus is provided including means for focusing a light beam with a concave holographic grating, means for passing light reflected from the grating through a step order filter to an array detector and means for processing signals from the array detector. The spectrometer permits monitoring a plurality of grating orders simultanously without mechanical scanning.
