593 Rigel Module extraction

[badboybilly]

I've seen the 532 modules u are talking about although they look similar I believe they are slightly different, in this 594 there are no set screws, you tighten the KTP crystal by threading it all the way down from the top, then to adjust the NDYV crystal there are 3 small threaded holes in the sides and they use special screws to apply pressure while all crystals are already tightened down and adjust in direction needed for alignment!

Is this the module you mean, it looks similar but yeah it looks like it has set screws on the sides but anyway should be same purpose!
