Abstract

The DESA material is an ultra-fine grained silver bromide emulsion referring to the name of its four inventors (D)uenkel, (E)ichler, (S)chneeweiss, (A)ckermann of the University of Applied Sciences in Berlin, Germany. The thickness of the dried layer is between 5 and 7.5 μm, and the mean grain size is by about 15 nm, as determined by TEM. During manufacturing, emulsion precipitation and coating are separated strictly from spectral and chemical sensitization. Thus, a high performance could be obtained. Resolution is estimated higher than 8000 lp/mm. Sensitivity amounts to 80 up to 120 μJoules/cm2 for maximum diffraction efficiency by recording Denisyuk white-light reflection holograms at 632,8 nm (HeNe laser). The paper provides an insight into fundamentals of the ultra-fine grained silver halide technology together with new challenges for further developments under theoretical and practical aspects.
