I've been using these, they're marked as OD 7+ from 190 to 532nm. I got them for use with a 40W 450 nm laser but they're extremely effective at blocking the 385 nm light my projector operates at.

These are pretty good. I like that they have the transmission and OD on a chart. Its making me nervous about my yellow ones because they have no rating for higher than 360nm.

Ah nevermind I just checked and the protection goes from 190nm to 525nm. But regardless the light seems too bright/ intense.
