Cheap IR filter--remove IR?

Question

I'm looking at buying a cheap 5mw green laser. Its a true 5mw. I want to put an IR filter on it so it blocks the ir coming out.

Note to people: using black film=bad. that blocks the green beam I want and leaves ONLY the IR.

Answer 1

The slightly greenish glass is good for that.

Answer 2

If you just search for IR filter, you'll find a bunch of filters that block visible light and pass infrared.  Obviously you're asking for one that blocks infrared and passes visible light, so it would be easiest to one that blocks both infrared and ultraviolet.
