First of let me say that it was an excellent experience dealing with thanhtung. Great support and I will have no issues buying from him again. I haven’t had much time to work with this pointer yet but right away the increased power compared to the 16X BDR-209 Bluray Diode is immediately noticeable. Also the host itself is very impressive. I don’t have a spectrometer but the beam photos were a bit misleading. Compared side by side with my 16X BDR, they look very close in color. I would estimate the wavelength to still be 405nm ish. Overall I’m still quite happy with it. I will post more information as I have it.
I was offered this diode in another host by another seller a couple of weeks ago, but being multimode, and what he was telling me about the amount of divergence, I didn't. However, maybe I should have, just put a beam expander on it and problem solved.
