What transparent glass to laser cover?

[ultrashow]

Hi
I am building my new laser. Will be RGB. I want to use few gratings like: line, burst, maybe machado. So I need 30x10cm transparent glass 457-660nm to laser cover. Is it normal Anti-Reflex-Glas? Like that to picture frame? What do you think? Where to buy best quality for good price. In few laser shops I found from 80USD to 150EURO

Sorry for language ;]

These work great...also mounted in a nice threaded holder. I have tested to less than 2% loss. In all four of my RGB's.....

If you need something large, you may want to try this link:

I've not used any of these yet, but believe that others on the forum have.
I'm planning for a large output window as well and will likely cut one of 10" x 12" windows down to the size I need.

I also saw a really cool dmx controllable wheel that had 20 filters on ... price was very reasonable for the flexability it would offer Sub 200 i think ... if interested let me know ill dig up a link

That's the Polywheel from LaserVisuals right?

Laservisuals makes the whole enchalada, with DMX, these guys make the wheels:

I highly reccomend Peter's wheels as max visual bang for the buck!, especially if you put them in front of a scan head.

I needed some AR coated glass on short notice, found some very nice at a local frame shop (picture framing) they cut it to the exact size I needed, for about $60.
