Hologram Recording Materials
Holograms need a material to record interference fringes. There are many materials that can record fringes.
Silver Halide Chemistry. Theory and Practice of Making Silver Halide Plates and Development.
Silver Film Comparison Chart A quick comparison of the qualities of different commercially made films.
Dichromated Gelatin Chemistry. Theory and Practice of DCG Plates and Development.
Polymer Film and Processes. Many commercially sold holograms are made from photopolymers.
Photoresist. Taken from the electronics industry, this material can make relief holograms for embossing.
Coating Methods. Coating Gelatin on to a glass plate is an art in itself.
Crystals. There are many crystals that can record an image. The cost and exposure energy required is very high so they are not often used for holography.
Embossed Holograms. These are like the holograms seen on credit cards.
Gelatin. Used as the suspension medium to hold light sensitive particles.
