The multiport LPD 100 Log Detector is a useful photodiode amplifier designed to measure low light levels, below - 90 dBm.
Luna’s Log Detector is a useful photodiode amplifier designed to measure low light levels, down to - 90 dBm and produce linear logarithmic electrical signal. It come with two of four channel options. The LPD 100 is particularly suited to perform high dynamic range power measurements in closed loop related applications. For example, in polarization tracking, specifically when trying to track to a minimum light level, where generating a reliable tracker feedback signal could be a challenging problem.
- Calibrated from < -90 dBm to >10 dBm.
- Response greater up to 4 MHz
- Single buffered analog (SMA) voltage output
- Compact size
- Modular Design
