Hi
This thread as another continuation of that one called "Gatling laser":
but here my next project will be to correct 7 collimated beams from an intact NUBM44 block with closed can diodes instead of 8 beams from NUBM08 block with crappy focusing G-balls.
First of all, I needed to check if a close to perfect collimation of all beams is possible if all G-2 are fixed on a custom made plate positioned on the top of the N. block.
For this I let CNC workshop make me a plate with 16 holes each having the right thread. The threads made there were so tight that I had to widen them a little passing again the tap into all of the holes.
Now I fixed it on top of a light engine taken from an old v1 projector. Without fan its Al heatsink can allow to work at 0.5A for a minute without warming too much. The difficult part here was to discover which of the wires were + and -.
About one minute of work was enouth to find the right position for each lens - so it was possible to obtain all 7 beam spots as straight lines on the ceiling. And it looks that all LDs in the block were installed almost perfecly parallel.

Laser Gatling - getting 8 CORRECTED parallel beams from NUBM08 block
Hi, I am returning with another build about what one can do with a virgin NUBM08 block. Let us call it - Gatling laser??? You can consider this thread as a continuation of that one: https://laserpointerforums.com/threads/test-of-diodes-in-nubm08-block-all-at-once.103392/ but now I want to play...
