Abstract

In this paper we present the results of our research on the recording of SHSG holographic transmission gratings using the new BB-640 photographic emulsion, a red sensitive ultra-fine- grained emulsion from Holographic Recording Technologies. The exposed plates were processed following a process similar to that optimized by Fimia et al. for Agfa 8E75 HD plates but with the temperature of the bleaching bath modified to 70 degrees Celsius. This increase in temperature improves the diffraction efficiency but does not produce an increase in absorption and scattering, as opposed to what happens in the case of the Agfa 8E75 HD emulsion. The influence of the developer on various holographic parameters is analyzed and discussed.
