My "Golden Eye" does not lie
Anyone else compare the colour output of 445 LD vs.473 DPSS ?? I do not see much difference at all ???? Comparing a 473@200mW to a 445@1300mW. The output percieved luminosity is equal....which fits with the eye response curve ( See chart below pulled from Sam's Laser FAQ).
In my opinion...with corrective optics....445 IS the way to go...on a new projector build....but for an existing build ??? I do not know that I am going to "Open up the hood" ..yet another time...not for a single 445LD....
Perhaps "Projector#2".....Dual 445LD, Quad 638LD and LW green....Sheeeeze !!! what a Money Pit this Hobby is !!! !!! Anyone else see or NOT see much difference 445 vs 473....in the color area....not beam quality....DPSS is still the SS King there !!
