Nice, so I would not recommend water based backing as it will swell the emulsion and the image might vanish at least while it is not dry. But maybe it also damages the hologram or alters color. Anway I would recommend to laminate it with a self adhesive black foil, as it is a dry process and easily ...

Hi, can you post pictures of your table(s) ?

How are your tables connected?
What does the michelson say, when built over two tables?

Did you check path length by doing the splitbeam holograms?


Motion is critical to every component after (and including) the beamsplitter.

Hm , i think it will work because that's the way they did it in the eighties .

I'm also interested, how can I reach you by mail . Or send me a pm through the forum.
What's the difference bwtwen 8e74 and 8e75?
I am in Germany

Cool

Welcome back!
I miss the discussions here on the forum as most is happening on fb , but I think fb isn't good for discussing because you don't find anything a short time later .

What are you interested in? Silver halide or dcg? Denisyuks or split beam? Red or green? Color?

A few pictures of my setup

Welcome to the world of holography. The difference between this two diodes may be the coherence length and the tendency of doing mode hops. So a diode has to be tested, if it suitable for holography. Some are, some not. I would say it is normal that you have to do many tests before getting any good ...
