You know now I think of it I did not offer those NDB7675 20mm 2.7A overdrive units for very long as they went out of stock after maybe two weeks of offering them and did not relist them any of the times they came back in stock but I had sent out maybe 15-20 of them even with the big warning about accepting the risk. I had assume I would have had heard back about how long they lived. I was of the opinion they would would be dropping like decanned G-Ball diodes in china made 8W/10W/15W CNC modules.Yes, Jordan, that is the same diode. I have another unused one in my stock, but thought it would be easier to exchange the diode in the NDB7675 build with my M462 since it has a 1.8 amp X-Drive. Then I can use the 2.4 amp driver in a new host with the NDB7675. Felt like the thing to do as I got very little shift in wavelength on that diode at 1.8 amps.
Yea and I do want to make an adapter that can thread in my modules to hold the extra lenses but what I have seen on those units they want the colimator to be as short a focal length as possible even preferring some F2 named colimmator that I think has a shorter focal length than the DTR-G-2 to get a nice correction with the multi mode diode.The NUBM07 could be used with GBall intact by placing another backwards GBall inline or I have used a backwards G2 but a backwards GBall would be better, then your normal collimating lens, the divergence out of the backwards GBall will be in theory the same as the raw output.
