High-efficiency silver-halide sensitized gelatin holograms with low absorption and scatter

We report for the first time the results of a comparative performance study of silver-halide sensitized gelatin (SHSG) holograms recorded in the familiar Agfa 8E75 HD plates and the new BB-640 plates manufactured by Holographic Recording Technologies. High diffraction efficiency (approx. 90%) and low absorption and scatter (approx. 5.4%) are the distinguishing features of the BB-640 plates, given the fact that both kinds of plates have been prepared and processed under identical conditions. Thus, in summary, our investigation reveals that high quality SHSG holograms could be obtained using the new BB-640 plates.
