That laser pointer looks awesome, nice host!

How does the beam look like?

I’ll post up some night shots of the beam next to a 8W Osram 450nm/Blue for comparison.

As for the diode specs, here are the Ushio Spec sheets. With a G2 lense, the optical output gets near 1.9W, but the beam spot isn’t ideal with the G2 lense, at about 20’, the beam spot/pattern is about 12” wide. The G8 cuts it down to 6-8”, and I can add a Red spectrum 3-Element lens that will allow for about 40% reduction in the beam spot size at the same distance.
