Very. Nice , well done !

Yes all three lasers are bad , start w one color first. The photo polymer needs to be adhered to a substrate ( glass), with out it no hologram can be made … you need to do some more research (there’s plenty out here).. Yes get a PL-530 green ,and/or HeHe red laser. First get one color working . You ...

Yes have numerous lasers available, pictured below are the three different outputs , collimated, fast expansion or raw out …. $225 each

Do like the rest of us had to do at one time or another, shoot at night !

Thought i would throw a few observations on the pp film aswell, Depending on what wavelength you’re shooting at, because of the dyes will naturally absorb throughput light to your object ( Denisyuk set up). Green lasers light have the best throughput. The ability to be narrow band is an advantage if...

Hey just got an order in of Hx-200 , if u need send me a PM
Available in 4”x6” packs or in 12” roll / meter ..

Well said Dinesh! , would the fact that things like thickness coating, processing/development, also affect the spectral response? w DCG and the correct processing it’s color response can be vary throughout its depth ..yes ?

Custom 300mw Coherent Sapphire 532 laser system complete. Ready to ship, tested for SLM, a perfect laser to use for DCG and photopolymer…
$750 w USA shipping and 90 day warranty , out of country shipping will be paid by buyer..

This laser will require a heat sink

Joe, I’m not sure if you mentioned what laser you were using as I read through. But I find the PL 530 laser has a hotspot more so than other lasers do. What that means if you need to throw more light away on the edges and use that central version like you had to with, other typical Diode Lasers , in...

Can’t use thin glass as a splitter, needs to be thicker as the outputs need to be separated more, sounds like there are too close to each other ( like stepping on each other) causing interference bands… try a1/4” plate..
