Optical Power Meter
Optical power meter (OPM) is instrument used to measure the energy in an optical signal.
A typical OPM device consists of a calibrated sensor, display and measurement units. The sensor primarily consists of photodiode which fit to measure appropriate range of wavelengths. On the display unit, measured optical power and the wavelength being measured is displayed. Depending on the set measurement wave on power meter, measured power can vary due to the calibration of the device. Power meters are calibrated using a traceable calibration standard such as a NIST standard.
