Low Noise Lock-In Power Sensors: RM9 Series Datasheet

Source: MKS Ophir

The RM9 series of radiometers are designed to 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. The signal is passed through the 18 Hz chopper and the chopped signal is detected by the sensor. All signals not at the 18 Hz frequency are suppressed.
