Description
This material is designed for reflection hologram recording using CW radiation in the red spectral range (633nm – HeNe laser and 647nm – Krypton laser). The emulsion has sensitivity curve maximum at 640nm. Maximum diffraction efficiency ~45%. Grain size of this material is ~10nm. This emulsion has forth times smaller grains than VRP-M and PFG-01 (Figure1). Therefore, it is hundredths time less sensitive than fine grain emulsions VRP-M and PFG-01. Ultra fine grain emulsions provide a bit more clear image than fine grain ones, but are very soft and are not recommended for hobbyists and beginners due to quite difficult processing and shorter life time. The Characteristic curve is shown on Figure2. Peak emulsion sensitivity is around 1.5-2mJ/cm2. Exposure can be calculated using our Online Exposure Calculator. The spectral sensitivity curve of the material is shown in Figure3. Recommended processing is given in table below.
