Hi, Can anyone point me at a resource for a good holographic emulsion formula please? Single Jet, Double Jet or just a 3 part mix. I'm looking for something I can make that is repeatable and coat with a Mayer bar please. Or if you have a recommendation on a book that would be excellent too. I alread...

Hi Dannybee I did try PVA to start with but found it too water soluble to be useful. As soon as I dipped the dry plate in any kind of liquid it started to melt. Can you tell me how you managed to keep the PVA from melting please? Or was it a special brand? I am going to try adding a dye after I have...

Hi Martin, 5 -10x would be a lot to give up :) I'll guess I will keep doing that. I'm working on a very simplified diffusion method that allows me to make a lot of 10x10cm plates quickly and cheaply I have read both Jeff's and Han's methods and am basing a process on the supplied information but wit...

Hi, I have been making my own silver halide plates with varying degrees of success(and failures :) ) To pre-sensitise my plates I currently use an Ascorbic acid bath but am starting to look at TEA and other methods. I know TEA gives you about 2 x the sensitivity of an un-sensitised plate but can't f...

I may have to buy a full colour unit of you as well.

Hi,

The hologram looks nice and crisp.
May I ask what light you are using to reconstruct the hologram.

Thank you
Grayham

That is beautiful.

Hi, 90cm is enough room to do some good work. I've made some nice multi beam beam reflections on a 60 x 90 (2' x 3') breadboard with a spatial filter. I've also made some OK single beams on a 12" square slab on an inner tube with a HeNe My advice is to not be too binary and just use what works....

It's definitely an idea though currently I'm just enjoying working through everything.

I'm still looking for advice on a bar though if you have used one?

Kind Regards
Grayham

Hi, Could someone advise my on coating bars please? I will be coating dcg on to glass and read in practical holography I need around a 7um emulsion layer for DCG. The bar mentioned in the book states a #24 gauge bar but when I looked this up I think this was about 60um. I have found a UK source for ...
