First build questions! (thread formerly known as Ebay 100mW 405nm )

[BrianM]

So a while back I picked up a 20mW 405nm laser pointer for pretty cheap. It kind of got me hooked. Well, due to a series of unfortunate events, it ended up breaking and I kind of forgot about the whole thing...until now. I got to poking around on the interwebs to see if i could come across any decent deals, and found this. For the price, it looks to be pretty decent...something to get me back into things. Just curious what your opinions are on it or others like it (these).

Any input is much appreciated. If that isn't worth the money, what would be? I'm looking for something half way decent in the sub $50 range (as far fetched as that may be). Violet/blue is what I'm looking for, but I'm open to alternatives. Thanks in advance!

You do know that it is a "plug-in" module, not handheld? Just making sure

Techhood is a good seller (if I'm remembering correctly). The laser looks alright but not the best, there's 405nm lasers in handheld form on eBay as well, if that's what you're looking for.

Not too worried about it being handheld or not. Truth be told, I kind of like the idea of a plug in module for my purposes.

I can understand that greatly.

That does look like a very good laser for the price, in my opinion

So after doing a bit of shopping around and a little research, I think that I'm going to go with this build instead.

Seems like a whole lot more bang for my buck. I'll keep you guys posted!

Cool, PyroGadgets tutorials are very easy to follow

So in that build, he uses the $60 module from this site. Would the $90 one be interchangeable with it? I like the idea of the G2 lens.

Save the money. The G-2 is a fine lens, but has inferior beam divergence. It is only worth the money for the 405nm if you're primarily interested in maximum output. You'll have a prettier dot profile with the 405 3-element lens.
