A/W = Amps/Watt. It is the response for optical detectors and it less than 1 because the conversion of power (photons) absorbed by the detector to current is not 100% efficient. You use it to find out how much power is hitting the detector by measuring the current out of the device and dividing by A/W. So if you read a current of 0.05A from the detector with a A/W of 0.5 than means that 0.05/0.5= 0.1 Watts of light is hitting the detector.

Photoelectric detectors are rated by their response in amps per watt of optical energy falling on the detector. The response is wavelenght dependent. A typical Si photodiode has a peak response of about .65 A/W. The photocurrent is usually converted to a voltage with a load resistor.

A/W means Amps/Watt. Response is usually measured in terms of Amps/Watt.
