Two watts of 405 nm, or 410+?

That's a great looking laser, and a good price, thanhtung, very tempting; it ought to sell quickly! :yh:

Good luck on your sale. :beer:

Have you done any divergence tests, or have those figures?

I do not have a wavelength meter so I only predict wavelengths around that,
i have ever compared with SJ06 about some months ago, i see it is brighter than SJ06 but not fanciful violet as SJ06

That’s a really heathy looking host! Looks like it has a lot of heat sinking. Bet you’ll get a lot of run time out of this build. Best wishes with your sale. :gj:

Divergence test does not require a wavelength meter, just wanted to know how much the beam spreads per meter forward.

What part of the host is copper and what part is brass?

do you mean thís picture:
1, not len range 1m:

2, compare focus with lpc815 at range 5m

Re: FS: 170$ ~2W violet laser MM, host copper brass

The Mrads don’t seem too bad from the picture, I wonder how accurate this divergence calculator is?

Re: FS: 170$ ~2W violet laser MM, host copper brass

Maybe this "Yellow Copper" from Wikipedia. It looks a lot like what I would call brass. :yh:

Brass was exactly what I was thinking Jeff. :thinking:
Yellow copper is quite unusual.
