Re: Silver Halide Recipe / Formula please
Adhesion to substrate is main problem during processing. Archival quality is connected mainly with type of developement and namely with final wash. GP-2 followed by fix and properly washed is superior for long term stability, similar as B&W photography. Unfortunately, this chemistry cannot be u...

Re: Silver Halide Recipe / Formula please
For over 20 years, I have been using only my silver halide emulsion. Synthesis and watering do yourself on the glass and film. The main wavelengths are sensitized at 633 nm, 532 nm and 488 nm. I do and color. Some holograms on this material can be seen. https://www.ebay.com/sch/s_m_a_k/m.html?_nkw=&...

Re: Buzzing HeNe laser
What is the length of the resonator tube? It is possible that the power supply operates in the ignition mode. not enough working current 11 ma for work.I don’t recommend it for a long time, the power supply may burn or a high voltage will be blown somewhere, and then a high voltage will constantly b...

Hello
What is the polarization of all three lasers?
Is everyone the same?

Re: Looking for spatial filters
But now I have stopped using spatial filters and only use homemade lenses, they are much easier to clean and install. All my holograms are made like this.

Re: Troubleshooting : emulsion peeling off
All these holograms are made in GP-2 without bleaching !!Hey by the way Valéry I think I just ordered your telescope hologram on eBay ( Loïc )

Re: Troubleshooting : emulsion peeling off
I use GP-2 always without bleaching.Can we really « not » bleach a hologram ??
I thought light would not penetrate the braggs structure and would not play back as 3d image ?
The exception is if you need to make a hologram of a transmissive for 532 and 488 nm
Good luck
