Night Vision thermal sensor geometry

Well it's just a thermal TEE VEE. :LOL:

I aint seen no round TEE VEE's yet and they've been around since September 7th, 1927 (about 95 years)

So old fashion thinking as The King stated, still prevails today.
 
Round sensors are wasteful to produce with current wafer production methods.
Well at least someone makes round wafers. :LOL:
