We'll just have to wait. I remember when <1mW red lasers were $50.00 here, now they're as cheap as $2.00. Same thing will happen to 473nm lasers someday.473nm for me I would maybe choose another wavelength if this included gas lasers.. although I have only seen a few of those in real life (HeNe and Argon).
The "true blue" is just amazing - really beautiful colour, very visible (especially in the dark), and quite good flourescing abilities.
A shame it's so expensive..
Somehow, sadly, I doubt this.. The price drop of red diodes was mainly due to so many different devices using them for reading and burning as well as all those cheap pointers which were sold everywhere. The supply became huge, dropping prices.. while they could be mass-produced, lowering production costs.
But say you had a row of all the wavelengths listed and you could see all the beams infront of you on a nice foggy night, which pen would you go and pick up to play with firstSorry for say you this, but you had to make all the choices selectable, imho ..... otherwise, peoples like me, that like all the laser types, cannot decide .....
..... or just add a "all the existing ones" choice
All together, ofcourse ..... why limit your fun to a single one ?But say you had a row of all the wavelengths listed, and you could see all the beams infront of you on a nice foggy night, which pen would you go and pick up to play with first
