Four-Channel Optical Power Meter With Display Probe External

The four-channel probe external optical power meter is usually composed of a photodetector, an amplifier, a filter, an analog-to-digital converter and a microprocessor. In the measurement process, the optical signal is received by the photodetector and converted into an electrical signal, which is processed by the amplifier and filter, and then converted into a digital signal by the analog-to-digital converter, and finally processed and displayed by the microprocessor.

The working principle of the four-channel probe external optical power meter is based on the photoelectric effect, that is, the optical signal is received by the photodetector and converted into an electrical signal, and then amplified, filtered and digitized through the circuit, and finally the power value of the optical signal is obtained. Since it has four channels, the optical signal power of four different optical paths can be measured simultaneously.

In summary, the four-channel probe external optical power meter has the characteristics of high precision measurement, fast response, multi-channel design, etc., and has a wide range of applications in optical communication, optical fiber sensing and life science.
