Diffraction Optical Element - from Reddit & Material Sample Shop

Thanks to a thread that Rokakku made couple weeks ago (http://laserpointerforums.com/f48/di...tic-97303.html) I found this item and found it really interesting. They online store that sells these DOEs claimed that they were out of stock but, the shipping was actually a hell of a lot faster than I would've expected, especially being from Denmark. Copenhagen to Toronto in two weeks isn't bad for over seas + out of stock! I must say, I wasn't even expecting it to come in.

(Thanks to Canada Post, a DTR module and this got delivered to someone else's address. I'll be sure to have a word with CP...)

I noticed that this diffraction element that lower power lasers work quite nicely, rather than higher power e.g. class IV. It's just too much light scattered all over the place, and a bit of strain on the eyes. For all the images I'm showing, I used a 303.

Here's what it came in (I ordered two, both of which are in the bag attached via a chain):


I believe it's a plastic polymer, it's also barely visible unless under a black or darker surface.



Here it is in action! With help from the laser tripod to hold the 303:










Here's an attempt at a .gif, looks like the frames and frame rate were rather... unsuccessful but I tried to save a good chunk of what I could. The spinning globe animation really is quite interesting:
