The LIAD series Radiometers use a pyroelectric or photodiode sensor in conjunction with chopped CW or quasi CW radiation, using a digitally synthesized lock-in amplifier to reduce external noise to a minimum. With a compatible optical power meter, you can measure a calibrated power down to 300 femtowatts.
