Abstract

We made reflection gratings by using the gelatin of Kodak 649F spectroscopic plates. The concentration of ammonium dichromate sensitizer was varied, and reflection efficiencies of fully developed plates were measured in different reconstructing angles. During the development process we varied the washing time, the time interval between the washing and isopropanol baths, and the duration of the isopropanol bath. The reflection efficiencies were measured for each processing variable. Finally, the characteristics of the gratings were tested by varying the recording geometry.
