Hello I'm about to start building an isolation table in my garage. A reasonably big one 2000 x 1000mm. I have a good idea of what I want to do and previously have used inner tubes for the isolation and they work well. Inner tubes take maintenance and if you get a dodgy valve or they go flat for some...

Thank you

Thank you for the update.

Ed, Thank you again for the help and suggestions all of which are much appreciated and also thank you for the links. I will probably use the plates and film in conjunction to cover my bases while I'm learning however while I am messing with shutters and exposure times developer temperatures etc. I'm...

Hello Ed At the moment I'm still trying to work out what's what when it comes to film. I have a source for some plates but am looking for a cheaper solution while I get up and running properly, working out my laser power, exposure times, chemicals etc.. I expect to have quite a bit of wastage while ...

Hello I am looking for some green sensitive (532nm) high resolution film. I'm wondering if there is a commonly used off the shelf product that anyone has found useful? Xray film caught my eye recently and I am currently looking into that but figured I can't be the first person to try and find someth...

BobH That has given me something to think about. The pulsed laser is only a side project and expect it may take a year of thinking with some trial and error. I am going to start really simple with the holograms though, just some single beam reflection holograms while i try out a few cheap diode lase...

Hello All I'm new to this group so want to say hello first and also ask for some advice please. I've decided to get back in to holography. I used to make small holograms about 20 years ago with a 2mw randomly polarised HeNe and they were ok but not great. Lasers are so much cheaper these days so tho...
