Default IR blocking glass needed (Pics inside)

I have some green lasers from dx and we all knows their cheap lasers does not have IR filter.
I've checked the amount of IR of my true100mw pen, using a anti green laser googles to block the the visible green light and then used the camera from my mobile phone. I was scared, the pink dot that I saw in the camera was incredible bright, and I culdn't see absolutely nothing with naked eyes, except if I look at the camera display!
In other words: pure IR...






.


I'm wondering how can I buy one piece of IR blocking glass to install it in my lasers. I've tried to find them looking inside my old webcam but there wasn't any glass with the ccd...

You can also try omegabob on ebay. He sells discount optics at very good prices.. look for BG38 absorption glass.

BG38 was described as UV blocking glass. Sent him a message though.

BG-38 is the standard IR blocking glass. Here's a transmission chart that shows it's performance: Schott BG 38 transmission data sheet | BG38 Optical-Filters.com
It also does block UV.
