let me first start off by saying this isnt really meant to be a full review- this is mainly to show the color difference between 532nm and 520nm. it really amazes me how such a small increment can make such a visible difference!
A little while back, i bought a 520nm diode from DTR. I had seen the 510nm build by RHD a while back, and the idea of a new color of green interested me- although i was sure i couldnt get anything for an affordable price. that was, until the 520's came along. Pictures i saw made it seem a more 'true" green sort of thing, rather than the yellowish green of 532nm (at least, this is how my eyes see these two wavelengths).
heres the first picture- just the host with a semi-ok beam shot.
to get past the issue of beam splash-which my camera unfortunately picked up all of- i just slightly unfocused the shot. this actually helped in two ways- 1) it didnt get all the beam splash (mostly due to dirty lenses), and 2) it helped show the color difference a little better.
this is just another one-i think this is when the battery in my 520 started dying (gee battery, what nice timing you have. jerk.) However, this does show what 520 really looks like, kind of more minty-green. i think its a lurvely color!
aaaaand the last pic, a beam shot of the two. pardon the random junk.
so all in all, 520nm is a wonderful color, not half bad, and nice power. not too little, but since its green, a little goes a long way. this one is around 80~100 mW if i remember correctly (great memory, eh? its just that sometimes i forget my....umm...what?). A lot of people just want power power power, regardless of wavelength, divergence, beam spot, or beam quality. i really like having two different green wl's in my possession-but i want MOOOOORE!
i would really like a 561nm and 556nm at some point- but man, that sure is a lot of dough. but one can hope!
thanks for reading!
