The eBay link you provided for the 150-A-.1-C OPHIR headits common for people to sell ophir LPMs but keep the sensor. as far as that ophir sensor, to clear confusion up, the one i linked above is a 150-A-1-C which means 150W-A sensor, 1V/W sensitivity and calibrated for Co2 lasers
is not calibrated to 1V/1W like the OPHIR 20C heads.
It is calibrated to 0.1V/1W... and can only be used at 60W
with additional head cooling and 150W with Water Cooling.
Without additional cooling it is only good to 5W...
