405nm blue ray laser pointer

The blue ray laser pointer is the new favorite in the portable laser world. As for the brightness, it is much more bright than the normal blue laser at 473nm at the same output power. Plus, the colour is eye catching, it is not pure blue, but a little violet, make little cool, but romantic. I think it may be taken as a gift for girlfriend. Though it is only a diode laser, but we can make the beam divergence below 0.5mrad, it is very tiny angle, also the beam is completely round.

In a word, it is awesome!
