Where to get IR??

I was wondering if anyone knows where to get a IR filter to put into my green laser? It was sold without one which is unfortuate as i dont want to be using one without. I was wondering if any of you guys know where i can get one? I live in the UK and more than willing to buy a few. TIA.

Nova Lasers sells one relatively inexpensive.

I can sell you some high quality Coherent 1cm square ones if that's what you're looking for. $6 flat shipping to the UK at $13.50 apiece. The novas are also a good deal too though.

Cheers guys, i'll look into it. Ill get back soon.
