Can I use TEA for colour control of reflection holograms on VRP-M with an Argon laser?
Yes, if you want to obtain blue to ultra-violet colour of final hologram. TEA must be used for pre-treatment of the emulsion. • Can I use the VRP-M emulsion with a Neodymium YAG CW laser? Yes. • What is the smallest HeNe laser that I can use to make simple laser transmission holograms with the PFG-01 emulsion? There is no smallest size. Even with 1mW you can make excellent holograms. All depends on the exposure time – less energy of your laser – longer exposure time. • Where can I find the relevant chemical products for holography and what equivalents can one use ?
