Re: Zilux Photopolymer ...

Curious what the sensitivity is like at 488nm vs 530nm, if you get a chance to test.

I want to ask what their pricing is like, but I see they require you to sign an NDA before even beginning product availability discussions :(

Re: Laser pico projector for making color holograms

Dave, where are you getting these pico projectors? It seems that they are discontinued. Do most other pico projectors work the same way? (Using lasers)

Re: 530nm laser diodes tested @75mw SLM

Great work you've done here, I saw some of the holograms Travis made with these lasers and they were fantastic.

Price point can't be beat. Hope some prospective holographers find these well!

Re: Crowd-fund & share your passion

The holograms shown in your examples video are brilliant! Very concrete looking, truly like a window into a box with the real object!

What type of laser and formulation are you currently using? Are these all recorded based on transmission masters?

Re: Chinese figurines and random stuff

I think you contacted me by private message, but here's my response for posterity: I use Knox gelatin. Let me just list some things about my setup. I use a 488nm 200mW laser, often exposing at 150mW or so. My DCG formula is 200-21-1.5 (water-gelatin-potassium dichromate) And some answers to emailed ...

Re: D.I.Y. holographic photopolymer

Somehow you have got to have the material all gelled to start with and then able to be made even more gelled in the light struck anti-nodes so that their refractive index is greater than in the lightly gelled nodes… .….as demoed beautifully in DCG. What if you were to expose the entirety of the pho...
