gilver re: "Yesterday's NR, highlights HFET and the fact that they have optimized 2 out of 3 components and has us again focussed on the positives"
My understanding is that the detector and HFET are "in place" and there should not be any unexpected issues, however for accuracy I'm not so sure they are completely done.
From yesterday's NR (bold is mine) "Two of the three critical individual pieces of an integrated opto-electronic product are now in place and undergoing their respective optimization cycles".
So they are not optimized, but likely this is just a formality and not a big challenge. Perhaps the fully optimized detector's responsivity will be even better than previously announced.
Good luck!!
