How is the divergence compared to NDG7475 or NDB7875? (With G2, 3ele, G9...) Are those "ball" lens any good? Can they be mounted for focusing or something similar? I see everyone talking about the power, but some people prefer good beam specs.

Any updates?

Having both is actually really useful and neat. Just don't use it if you don't like it.

Exactly. I'm subscribing for news. This is so exciting :D

Very nice! :beer:

Are you sure? Aren't there single-mode 445nm diodes? Or are they rectangular too?

Nice mod! :beer: I'd like to see some pics of its abilities (range, spot at night...).

Me too! :beer: I'd sacrifice power for better beam and dot anytime. Power has become dirt cheap.

Wow, this is so exciting! :wave: Can't wait for the other wavelengths to follow!

Threads like this are really annoying! What kind of logic is: "I buy something, then I ask for advice about it"?

Re: Frankenstein 445nm 3.1W With Lenses Recoated LG Beam Expander. Nice laser, however it should go into 445nm section. :beer:

I think some people are too paranoid about safety when talking about power.

Nice, very nice! :beer:

Very nice laser! Gotta love the side switch! :beer:

Re: FS: 5 New Custom Hosts. 2x18650 Wow! These so awesome! :D I'd buy one or even two if I could... Although I prefer a clicky side switch and 26650 batteries. How is the module held in place? With a screw? If so, are there other options to hold a module (like thermal epoxy, but removable)?

Now that is a beautiful color! :beer:

Now that is a good looking laser! I love side buttons! Which batteries does this laser use (2*16340)? Could you post some pics of the beam and dot at night? What about splash and/or wings? Divergence?

Yeah, but he is doing a single mode build...

Some have used cylindrical lenses to make the wide beam of multimode diodes more squarish. But I don't know whether you can improve the divergence of a singlemode diode though. I heard using the correct lenses with the correct diode/wavelength produces better quality beam but I am not sure...

Exactly. 2x 200mW and 2x 50mW is great to wear on a hat in a crowded area. Someone should test this stuff.
