Is it safe for me to let friends use the old style if its limited exposure outdoors, no shinny surfaces around or roadsigns? If not perhaps they work better for 405nm?

:D Can I buy a pair of new style? Maybe 1 or 2 old / guest one as well? :undecided:

Very interested in doing knife edging properly. Particularly selecting lenses to reduce the size of the final beam. Could you share more about it & perhaps links if you have some? With 1W of 445 now available cheap red is such a weakness in RGB.

:thinking: Sorry if I'm mistaken but it sounds like you missed the fact that he isn't selling online at all. There would be no mailing then.

Glad to see someone still building with other colors than 445nm.

I'm not using them for burning by the way. You can collimate these with an aspheric? So fast & slow axis have the same divergence? I'm looking to use them at ranges of 10-20ft. Projecting onto a surface, hopefully without the fast axis being too much larger then slow. Your answer refers to the...

Whats the divergence of the 980nm LENSED diodes? Might buy a few by proxy. Also divergence after optics on the 7W TO-3 980nm diodes w/colimator?
