PFG-03M, red sensitive

804
PFG-03M, red sensitive holography plates, high resolution

Rot

The Material PFG-03M has smaller grain (8-12nm) than PFG-01 material (40nm) and high resolution >5000 lines/mm. One can see better luminance due to small scattered light, but need high exposure power. The fine grain emulsion is suitable in particular for reflection holograms.

  • Description
Tab 1

This material is designed for reflection hologram recording using CW radiation in the red spectral range (633nm - HeNe laser and 647nm - Krypton laser). 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 Fig.2. Peak emulsion sensitivity is around 1.5-2mJ/cm2. The spectral sensitivity curve of the material is shown in Fig.3. Recommended processing is given in table1, recommended chemistry - in table2.
