Hello once again everyone. I’m finishing up my build this week, just need a bandpass filter rated for a 780nm wavelength. I found an ebay store that sold bandpass filters, but nothing that had 780, has anyone else used this or have a recommended site to check?

By the way I’m using an xbox live cam, not that it matters I guess.

*UPDATE*

would any of these work? http://shop.ebay.com/items/_W0QQ_fromZR46?_nkw=780nm&_fromfsb=0&_trksid=m270

I just ordered the 3rd one down...

I ordered one of these:

Let us know how that filter works out, I think there are quite a few people trying to do LLP with the AixiZ lasers.

Damn, those seems perfect for the aixiz lasers. Please, let me know how they work

I know this is a old thread but how well does these filters work with the lasers?

They work ok It’s alot better than the other stuff I have used, like floppy disc and overexposed negatives.. Go for it

Unexposed developed film will do the trick as well. It did for me. It’s just perfect, inexpensive and great results! I am using it with the PS3 eye camera and IR laser module 850nm.
After googling a lil bit a found this:
