Personal Lens Preference for 445nm?

[IsaacT]

Is it feasible to use the 9mm stock lens with a 405nm laser? I have a 12X, and they sometimes recommend the G1. Well I don't have the G1, but I have the 9mm stock lens. So just curious if it works.

Thanks,
Isaac

The AR coating I believe is the same for 445nm and 405nm. So yes

Id be curious to know if we get anymore power from a 405 using a 9mm lens. Might make that 1watt mark that much easier to hit!!!!!!

I can't even imagine a 1W 405nm laser. I know someone on here made one, but that just seems so....ridiculodangerous. I mean....my 550mW 405 burns like crazy, I can't imagine what a 1W 405 does.

Its probably a lot like that, but purple.

But seriously my dream laser is a 1W 405, I cant get enough of that wavelength. Imagine how bright things would fluoresce with that much 405 :drool:

You should try the 9mm lens on your 405 though, since its single mode the g1 lens makes it a crazy tight beam that you can still focus very far away, unlike using it with 445 multimode diodes, should be the same for the 9mm, since it has the same focusing specs basically.

It looks pretty bad. The focusing is terrible. You either have a very tiny dot or you have a giant ugly splash. There is no in between. Its weird. I think because the 9mm is corrective optics for the 445, it is not meant for single mode goodies.

Maybe....

Well, it was worth a try.

I'm with jakeGT: I just use the regular "working lens" that is AR-coated for 445nm/405nm. I figure if I wanted more power I'd just use the money I'd save over a G1/G2 on a second diode.

yep. cant beat that beam and dot quality on the 3 element glass.
