Reprocessibility of Dichromated Gelatin Reflection Gratings

Abstract

Abstract The reprocessibility of dichromated gelatin reflection gratings is studied. Reflection gratings developed in six slightly different ways are reprocessed after three years storage. Reflection (diffraction) efficiencies are strongly decreased during storage. After reprocessing reflection efficiencies are close to the original reflection efficiencies. Restoration is better when the original reflection efficiency (RE) is not very high (RE <90%). When, the plates, which are rapidly dehydrated during development procedure, are reprocessed using slow dehydration, reflection efficiencies have often been even better after reprocessing than one day after exposure and the original development procedure.
