green can be seen the best, can white been seen even better?styropyro said:If there was that would be one heck of a big pointer. All three diodes plus cyrstals for the green plus all of the mirrors to combine the beam would probably take up space and don't forget the heatsinks for all of the diodes. Would be pretty cool though.
look at this here, it shows a guy with 3 laserpointers and he aimed them all at the wall and its white.SenKat said:Nope ! Take a look at the charts posted in numerous locations on here - it shows the human eye's sensativity to certain wavelengths - and green is WAY up the scale - I believe it is 555nm is the best you can get for visability ? (I think)
Sorry to be so cynical, but I've heard much less sensational talk behind closed doors from WL, and been disappointed. I've heard a lot of talk, and seen very little action. What action I have seen has always come far later than anticipated. I'm sure WL would like to debut an RGB, but I have my doubts we'll see it anytime soonthinklasers said:there has been some talk behind closed doors for an rgb spyder in the near future, but you didn't hear it from me!
that would be quite an engineering challenge - for one thing you'd want the beam diameter and divergence to all match too, it would be nice thoughstyropyro said:If there was that would be one heck of a big pointer.

the only options i can see would be red/cyan, and while red is cheap i haven't even seen a handheld cyan (though i'd love one!), or blue/yellow, both of which are expensive (and most "yellow" out there seems more orange)...unless violet/green would work?Ragnarok said:It is possible to make white light with only two complementary colors, perhaps more economically than with RGB.
