Description
Summary:This report describes the modification and updating of the Remote Raman system at Edgewood Arsenal. Several technical and engineering innovations were incorporated into the remote Raman system. These included: (1) Replacement of the existing KD*P (potassium dideuterium phosphate) doubling crystal with a more efficient RDA (rubidium dihydrogen arsenate) system. (2) Installation of a motorized drive on the polychromator positioning rails to facilitate alignment in the X and Y directions. (3) Addition of new mirror mounts in the ruby laser to increase long-term optical stability, and (4) The correction of various minor opitcal and mechanical problems. The modifications have resulted in an overall improvement in performance, stability, and ease of operation of the remote Raman Spectrometer.
