The smaller host is a skyray I bought from Rich ( Lifetime17 ) he made the pretty heat sink with the copper insert, he also made an adjuster but I like seeing the copper insert, it holds a 100mw osram 520, the larger MX-900 I have literally dozens of and I can build in minutes, they are ultra simple with ample room to work, it holds the NDG7475 running an 1.8a X-drive.
I had to go out and eat some dinner, just got back and put it together, it was in my mailbox today at 6pm, the MX-900 is a very easy build.
BTW: The osram has a 3 element 520 lens and the MX-900 has a 2 element 520 lens, I'm not sure what difference it makes, I may swap them and see although I typically don't replace a lens unless it's burnt or too dirty to clean if I can help it, the less we expose our diodes window the better.
@ Paul: Sorry I don't have a power reading, I still don't have a LPM, I fully intend to PBS cube 2 x NUBM44-81's or what ever comes next, I want to be able to read double digit wattage, hopefully triple digit wattage before all that long.
I like pretty beams, DPSS are the best to look at and I can enjoy 100mw as much as 1000mw as for pointing, it's subjective, if you pick up a 5mw it is cool and fun, but pick up 100mw and the 5mw looks weak, but pick up the 5mw later and it's fun again.
I am a burner at heart, power matters the most to me when it can do useful work, or entertaining work, I'm saving my pennies to go bigger, the auction I won was 124.00 for all 3 diodes shipped so how could I not be happy with that, if the 7475 puts out 875mw or 1105mw at 1.8a it really doesn't make a big difference to me, but it is very cool and I should get the 150 dollar LPM, I can easily afford it, I just haven't done it as I'm torn between visible and non visible power for my wood burning art and want to invest in the most useful LPM and lets face it, I'm a cheapskate but I want good tools, so I choose them wisely, which is often slowly. :beer:
Hey Red....nice work. How much does that MX 900 cost by the way. I was out the same time you were experimenting with my new 1 W green in the 10 X jetlaser BE....man, I really love that green!
You are right on target about green. I mean everyone knows are eyes are more sensitive to it. I have a relatively weak 75 or so mw DPSS greenie and it never ceases to do it for me...
But....if only we could converge 50 NUBM44s that would be one burning mother of all burners! Keep on lasing brother!
