HOLOGRAPHY, PHOTOMATERIALS FOR MASKS AND HOLOGRAPHIC, FILM, PLATES, CHEMICALS

Slavich currently produces and supplies both Certified Silver Halide and Dichromated Gelatin emulsions for holography applications. The table below summarizes all the materials presently available.

- The fine grain, green-sensitive VRP-M emulsions for both Pulsed and CW laser recording of holograms.

- The fine grain, red sensitive PFG-01 material for CW recording.

- The ultrafine grain emulsions PFG-03M (red sensitive) and PFG-03C (panchromatic) for CW laser recording.

- The long-life Dichromated Gelatine emulsion PFG-04 for recording in the blue and green spectral ranges.

All of the Silver Halide materials are available coated onto glass or TAC film substrate and cover a wide range of sizes.

We are grateful to Sergey Vorobyov for the technique of latensification. We would also like to acknowledge the work of Hans Bjelkhagen and Nicholas Phillips, on which much of the chemistry listed herein is based, as well as that of Bernadette and Ron Olson for the technique of colour-shifting by D-Sorbitol.
