Hey there, yeah i thought I got lucky one time and scored a 30 by 10 sheet of "anti-reflection" coated glass for $5.00, but instead I'd sent Dave on a mission to get a piece of frosted glass. The stuff is transparent only if you hold a painting or something of some naked lady's vagina up close to the glass, but otherwise is more like lumia than anything else.
meh.
I'm still waiting for the glass sample - looks like it didn't make it out before christmas. I'll hound the suppliers next week when they get back from christmas break.
slack fuckers ;)
Once I get a sample of this new stuff and determine if it's suitable, I will post some prices up :)
Thanks for the interest guys!

Yeh I'll buy some pieces..

Okay.
So we got a sample. We have done some quick basic tests just now...
With our RGB laser...at near 0 degrees angle of incidence, ~126mw before the glass = ~121mw after the glass...
~96% total transmission... I guess the 4mm of glass in between the two coatings absorbs a bit of light. Still a massive improvement over using normal uncoated glass.
After including material, cutting & local freight costs, we could offer these out at $30AUD a pop for a 100mm by 100mm piece (plus shipping), or less if you buy quantities....
If anybody would like us to take any other types of measurements let us know...
-
:D I'll take one...how soon can you get theses or are they already in hand? I can cut round or square....for that matter any faceted shape with many sides...let me know could use it.
-
I can get these within a week...
We just need to work out a safe and inexpensive way of shipping bits of glass around the world.
Any suggestions ?

:D Wrap each glass window with optic grade tissue/foam. Sandwich the part in between heavy card stock or better thin plywood about 1/8" thick. Tape the sandwiched components to avoid movement. Ship in box padded with foam or the like...giving plenty of room....should make it OK.

What about a cd/dvd case in a jiffy envelope?

I could use a piece if shipping to USA is reasonable.
-
How much will postage be to the UK?

Wow.. awesome response already guys. Thanks for the suggestions. I kinda like the dvd case idea :D
might need to "test" that with a normal *cheap* piece of glass.
Anyway - once I have the weight down-pat, i can post the shipping to the diferent destinations.
It would probably be most economical to use EMS...
