laser safety glasses - another supplier option
Submitted by akbentley on Wed, 06/18/2008 - 16:54
We found we needed to order more laser safety glasses so that everyone working on the project could help with the alignment process. Our department's electronics technician was concerned that the Wicked Lasers glasses didn't have optical density information stamped on the frame. Customer service at WL didn't know much about the glasses' specs, so we ordered our extra pairs from Phillips Safety. Here's a link:

We ordered the LS-AA-33 model - $80 each. (Compared to WL at $40 each, so more expensive.)
We are eagerly awaiting the arrival of our printer so we can move on to the next step. We'll keep all of you posted.

Laser goggles
Yes the WL goggles are on the low end but we are not needing protection from a really high power laser and so even an optical density of 1 at 532 nm will take a 25 mV laser down to 2.5 mW rendering less powerful than most laser pointers in use.
In fact we just measured 110 microwatts transmitted through the WL goggles from a 40 mW laser meaning the optical density is more than 2 at 532 nm.
More dangerous is the reflection from the laser google which may be in the 5 to 10% range like the OD 1 argument above.
