Well, I certainly believe you! Do you have any idea why IR photons are
so hard to detect, or why the arrarys are so small? They have more
energy than microwave photons.

Yes, they do, but I'm curious as to why you've brought up microwaves. Is
there a microwave array or detector that has more pixels than your
run-of-the-mill mid-IR array?
