Noise Measurement——Silicon Photodetector

      Noise measurement adopts silicon photodetector to measure the laser beam after attenuation, laser optoelectronic signal shows on oscilloscope via adjust variable attenuator, and noise signal shows by adjust oscilloscope. Laser system output power stability can be judged according to noise signal.

Testing Instrument: Silicon Photodetector

Noise measurement
        Low noise, wide-band amplifier
        Fixed and adjustable gain module
        0-10V output
        Compatible with SM1 thread and other SM05 products
        Linear power supply
