Re: compact RGB collimated unit

The alignment problems are beyond me though you may be able to resolve your polarisation problem by rotating the diodes in their housing if they allow it.

I suspect they are glued in but access to the diodes looks easier than the green.

Re: Anybody still here?

I am :)

I use the forum mainly for research though do post.
You do get a quicker response off Facebook though when looking for help.

Re: Silver halide sensitivityy enhancer

This is an interesting read. So do the formate ions bond to the AgX when the AgX is exposed to the formate or on exposure to light? If it's on exposure to the formate then i'm guessing you could wash the plates after the formate soak in a similar way you do with ascorbic acid. This may stop the colo...

Hi Sergio,

I sent you a PM but it's still sitting in the outbox.

Have you seen it or is this a message board problem?

Re: 3D Silhouette

why does it have to do with holography? Maybe there’s a forum somewhere that has to do with your 3D printer and it’s software. With a 3D printer you can make mounts for mirrors, lenses, beam splitters, plate holders etc that work really well. And you can 3d print models and make holograms of those ...
