Do you guys have any good sources for effect glass and gratings?
Star filters, hot dot patterns, linear , Nebula and Aurora ( Types of Lumia)..
Ever hear of Dimple Glass? We used to use that one.. Very cool.. Basicall that one was like a nebula, but had only One big dimple in the glass...
I got some rather nice patterned clear art glass off eBay.
COOL, I will watch for it on EBAY....
Need to make myself a little effects wheel with some cool effects...
You can get some of the best effects with boring every day objects and "interesting" placement ;)

my *trick* to that one is a cut crystal drinking glass, its shown in the video ;)
Hey Spec, Cool Effect.. I remember spending Hrs trying different objects and finding some cool stuff... Kinda hard to mount some of it though, so it never made it into shows....
I guess the stuff im looking for is mainly holographic and diffractive stuff..
6 point satr filters, Wide space DG , Tight DG, Linears and radial fx.. That stuff..Usually came in sheets and you could cut pieces off for mounting on wheels or fx arms
..
I will keep lookin!
P.S. Cool Avatar, How did youdo it? It looks like 3 rectangles Sphere wrapped and xyz rotated....
There was a guy on ebay selling "pre mounted" diffraction gratings in slide projector housings... Ill see if I can track down his email for you and get him on PL ;)
The avatar: I didnt make it! I dont remember who did or what site i got it from but the look of it said "keeper". One day Ill make a show incorporating those pieces running around a sphere or something. ;)

The lenses are cheap plastic holographic film. You can cut out the lenses and hot-glue them to just about anything to make instant diffraction grating effects.
I've found a few different types of lenses. Some are line gratings, and some are grid style gratings. (Think of a tic-tac-toe board of beams, and you've got the idea...) Personally, I like the grid style better. (Like the ones in the link above.)
I don't know how much power they can handle, but from personal experience they can handle a couple hundred mw at least! They are really cheap (like $1 a pair if you buy them in lots of 10 or more), so you can buy several and just experiment without breaking the bank.
Good luck!

Thansk for that.. I will search some out.. High space diffraction and 6 point star filter buing first prioritys
Hey Carey,
I can custom manufacture various Lumia wheels either mounted on 1 RPM motors or standalone " you save $$ and you mount them " .
Anyone interested PM me.

intrested yes :)Quote:

I`m intrested maybe..
I have a "lumia" , a old motor from a disco-ball , and a custom cutted glass..
And I use it on a 100mW red laser :)
But to mount inside my laser scanner i think i need a more stabile lumia motor :roll:
Maybe this is the one your'e thinking of?Quote:

Thats him!
I kept searching for "Impossible Square" as thats what came on the business card in the package. Standard search didnt show anything ;)
Really thin gratings mounted in 35mm projector slides. Not perfect for laser stuff as there is quite a lot of back reflection. Tested them to a .5 watt no problem.
I think this is the same glasses that i did steal from my school.....
Then can split lasers (if you want to) but they was ment to split the SUN light :)
we did get a nice rainbow of colours :)
Hello,
I hold quite lot of diffraction grating film I bought few years ago (a good opportunity since hard to find now...).
I have tested them with 1,2 & 3 watt Lasers (dpss at 532) : they work fine !
I will be able to test them with a 10 watt 532 dpss soon.
Moreover, they are 150mm x 150mm big !
Since I want to be able to afford coming on holiday in US next summer...I'm ready to sell theese gratings if several people interested !
I search also for Pangolin system : making a deal with an exchange is also possible ;-) !

PS : I can also buy DAC and/or softs here and resell them when coming in US (then you save shipping & insurance cost...and I can have good price if buying in quite quantity).
You could try making your own lumia glass by dropping small beads of poystyrene cement or other similar adhesive onto your glass / perpsex disc, leave to dry and then add more drops and so on. I have got very good results from this method and its cheap and easy. Also other glues with different polymers may work, they don't have to be solvent based. Not sure on how much power they could cope with, i guess several hundred mw should be ok, escpecially if rotated at ~0.5 rpm.Quote:
