Yep, I plan to get longer screws sometime in the next few days. The only problem is that there aren't really any places for them to screw into the O-like so the fit wouldn't be very secure, and with the substantial weight of the beam expander it might very well slide off.

Just received the Jetlasers 10x beam expander. Although none of the adapters that it comes with fit the o-like, I've found that if you hold the expander straight onto the face of the laser it actually fits pretty well - you just have to hold it there whenever you want to use it, which can be a...

Nope, not yet. I'm ordering from Jetlasers and they're supposed to ship pretty fast, so hopefully I'll get it sometime in the next week or so. Will definitely post an update once it arrives - I might have to modify the adapter a little bit before I can use it though, as it's meant to screw on to...

Interesting. I figured the o-like with the built in beam expander would have fairly good divergence but 0.3mRad is fantastic. I plan on picking up a 10x beam expander for 400mw shortly and will definitely post an update once I get it mounted to the laser and test it out. Assuming my laser has...

I agree with what you said about the 2.5w 445 vs the 400mw 532. I was expecting the 400mw to be a fair amount brighter. That said, the actual dot of the 532 might very well be brighter than the dot of the 445. I think the 445 could be lighting up the room more in part due to how much bigger the...

Hey 2100, thanks for the reply - that light meter idea seems pretty intriguing - might need to pick a meter up at some point and give it a try. The main way that I've been trying to judge the power of my laser is by seeing how much it lights up a room when pointed at a white wall. At night it...

Thanks InfinitusEquitas for the welcome and quick reply. Good to know that it's practically impossible to gauge power without a power meter. I figured that was the case but just wanted to make sure. The main reason I was concerned about the mode hopping was because I thought that that might be...

Hey guys, I recently received a crown upgrade 400mw green laser from O-like. Shipping was super fast even with regular mail (not DHL or EMS) - Susie sent the laser out Monday July 16th and it got to me in Ohio exactly a week later on Monday the 23rd. Not bad. First impressions: the laser is...
