Hmm, visually I haven't noticed a drop in power. I don't have a power meter yet but I'd like to get one to at least categorize this module. When I do I'll post the results here, as well as any discrepencies in the stated power vs. actual. Specs say 80mW @532nm, but we'll see what actual measured output is once I can filter out the IR spillage. Being a cheapie chinese laser I'm sure there's at least a "few" mW of IR spillage out the front.
Anyone know of a source for relatively inexpensive wideband IR (808-1064nm) dichros, and flex mounts/MM1s?
