ThorLabs Lock-In AmplifierUSED
The LIA100 consists of a programmable AC input amplifier, a monolithic phase-sensitive detector (PSD), and a two-stage programmable output low-pass filter. The input amplifier is a two-stage design with an adjustable gain to boost the modulated input. The PSD performs a frequency translation to shift the modulated signal back to its original base band DC. The output filter is a two-stage low pass filter to remove any residual harmonics from the output of the PSD. The output filter has adjustable settings of 10ms, 100ms, 1s, and 3s. In addition, a user-defined time constant can be set by simply adding two capacitors to the LIA100 printed circuit board.
