Power meter

An optical power meter is equipped with an InGaAs sensing diode and dynamic range of 75 dB. Two models are available: the FM8520 with a dynamic range of -70 to 5 dBm and the FM8520C with a range of -50 to 23 dBm. Both feature digital calibration and a memory that can store up to 250 measurements/wavelength in dBm, µW, or dBr.
