Got my diode today from DTR. Got a chance to do some quick tests. I used the green coat 3E lens from DTR. EDIT: added china G2
Threshold was at 70mA
mA---- mW 3E---- mw G2---- nm
70------ 3.7------ 3.5------ 513
100----- 17.6----- 22 ------ 513.8
150----- 44------ 51------ 514.3
200 ---- 64------ 77------- 514.75
250 ---- 84------ 103------ 515.2
300 ---- 101----- 120------ 515.3
350 ---- 116----- 143------ 515.4
400 ---- 129----- 158------ 516
Spot size with 3E ~ 5X9mm at 48feet.
I tried to look at the color difference between a 7475. They looked the same to my eye. The spectrometer showed the 7475 maxed out at 518nm at ~1.5A so really close in wavelength.
All in all really nice tight beam. Very impressed with the 3E lens from DTR. Has anyone compared the 3E lens and a G2 on a 7475? My 7475 is in a projector and hard to change lenses.
