OK, here's my question: Since AGFA stopped making their holotest materials, there seems to be a gap in silver halide materials for He-Ne holography. I'm insterested in starting doing holography. I've got a 2.6 mw he-ne laser, the mirrors and lenses to do basic transmission and reflection holograms, a dark room, and I'm planning on building a sand table (for vibration isolation). Now my problem is recording materials. One thing I'd like is to use stuff that can be developed by readymade (D-19 or whatever) chemicals. Since I'm not experienced in mixing my own chemicals, which some of the emulsions require, I'd like to use ready made stuff until I know what the hell I'm doing. To take a variable out of the mix, basically. I'd also prefer film to plates because of the expense of plates. Agfa 8E-75HD is still available from a couple suppliers -- jodon and intergraf. This can be developed with ready-mixed Kodax chemicals. There's lots of literature on using agfa. The downside is that it's expensive and who knows how long we'll be able to get it. The other options that I've found: Kodak hi-speed holographic film and plates- http://www.kodak.com/global/en/professional/support/techPubs/ti2433/ti2433.shtml develops in kodak chemicals, but has a low enough resolution that it's only useful for transmissions. Red star ultra - http://www.holograms.bc.ca/film.htm This seems like a good option but, has anyone used it? Any opinions? HRT's bb-640 plates - http://www.holographic-materials.de/ another good looking option, but they recommend aspecial developing procces. Slavich PFG-01 or PFG-03 - http://www.3deepco.com/ People have been using this and saying good things, but it needs special developing also. And I hear the latent imiga fades REALLY fast. So, for my beginning uses, Red Star looks to be my best option, but can anyone offer testimonial? Evan Bender 3rdtoad@geocities.com

I've been using BB-Plates with PyroChrome processing. Pyro requires a little measuring and mixing of two components (pyro and sodium carbonate) before processing, but if you're only doing a few plates a week it's quick and painless. Perhaps BB will provide film-based emulsion if enough interest is shown.
Pyro is just one of the processing techniques recommended for BB's, and it may be possible to get good results (for transmission holograms at least) utilizing the D-19 regimen (dilute your stock D-19 with 1 part developer to 4 parts distilled water for each tray used). They will send you a few sample plates to test.
I know that Steve Michael of www.3dimagery.com has been working with Slavich and may have a report on his website sometime in the future. I have samples of 50mm x 50mm film, but have not gotten to it yet.
I've seen a few holograms on Red Star and they look good.
One thing I DO know, and that is once you've got your exposure and processing down with the newer materials you won't miss AGFA at all. 204.170.70.14

The best plates for me is with no doubt the BB-640 plates. They give you much brighter results than AGFA, and you can use all the same processing formulas as for AGFA materials. The best formula for me is SM-6 dev.(easy to mix) and dichromate bleach when making reflection holograms. When making transmissions I'v achieved the best results when processing the plates in Ascorbic dev. and EDTA bleach. I'v recived some Slavich plates (PFG-03M) and will try them out within a few days. I shall make some tests on these plates with both He/Ne laser and a laserpointer, and use the russian dev. GP-2. rorasmu@online.no 130.67.15.250

I have had very good results with the Slavich PFG-01 for tranmissions and PFG-03 for reflections (http://www.3dimagery.com/films.htm) using the Infiniter 200 laser pointer from Quarton (www.3dimagery.com/pointer4.html). The infiniter 200 has a wavelength of 650nm and the reflection images are definitely in the red spectrum and not as bright as my gold images working at 630nm with a He-Ne, but bright enough! But using Frank's triethanolamine preswelling would definitely move the image color into the gold region. I used the stand Pyrogallol developer and dichromate bleach. 209.122.204.87

Hi Evan,
Send me e-mail with your post address and I will send you PFG-01 and PFG-03M film samples (free of course).
Best Regards,

HECTOR - Fri, Aug 13, 99 11:26:07 AM
I need to know if anyone has used the developer DX-80 OR LX-24? are these developers good for the rusian and german plates?. If there is someone from mexico on this web page, please contact me at my e-mail address hml@correoweb.com 200.38.195.71
Stas Zacharovas - Thu, Aug 19, 99 10:47:19 AM
Hi Hector,
Actually for the russian emulsion that we are disributing worldwide
you need to use the developers that was designed and tested by
manufacturers. You can find the only right receipts on our site
www.geola.com
And give me your post address - I will send you the film samples.

Does anyone know much about the Red Star film? Does Pyrochrome work well for this? Is it really only 1-2 sec exposure time for a 10mW 4x5 sheet? I'm thinking of trying it out. e_kelsic@hotmail.com 207.225.103.106
Steve Michael - Thu, Aug 26, 99 06:22:27 PM
Can you give me more information on Red Star film? Who makes it? Where can I obtain it? Once I have that,
maybe I can help. Thanks. 209.122.196.147

Here is a site for Red Star Film:
http://www.holograms.bc.ca/film.htm
I think its part of the Royal Holographic Art Gallery. Tell me if you get good results with it.

Thank you Eric. I've requested some film from them and will run some tests. I'll post my results on this forum and my
site.

Hi guys, just take a look to the "Red Star" recomended processing and compare it with slavich emulsions processings that you can find on www.geola.com
I think it will give you the answer what the "Red Star" is. And you can mail me personally to technical@geola.com - I will tell you the full Red Star story. 195.12.167.254

Hi, anyone looking for a high quality developer for the silver halide film, try "Rodinol", it's far superior than a lot of the others. 146.230.128.29
Eric - Sat, Nov 20, 99 05:00:55 PM
About the "rodinol" developer, what is in it? How about compared to pyrochrome or SM6? Any more information? e_kelsic@hotmail.com 216.160.141.127

Dear Sirs,
I am interested in holographic foil and "printing" equipement on it. I wood like ot to start with special security labels, special security car program...

Wow. Holography is extremely complex. But anyone with any brains in them should know that. I'm in eigth grade and am doing a science fair project on holography. I visited the links mentioned above and will go over them again later and as to whether I will purchase anything from them will be determined later. However, if any of you could post any other sites for possible resources such as film, mirrors, spreading lenses, beam splitters, etc. I do have, however, the laser necessary. Everything appreciated.
