The Anritsu MA9611A Optical Power Sensor is used with an ML9001A optical power meter. Specifications. Wavelength range: 0.75 to 1.71 µm. Element: InGaAs photodiode. Optical power measurement range Continuous light (At 1.31 µm): -70 to +3 dBm (0.1 nW to 2 mW). Optical power measurement range Modulated light (At 1.31 µm, 270 Hz): -80 to 0 dBm (10 pW to 1 mW). Absolute Measurement accuracy (-23 dBm) for wavelengths other than 1.3 µm, specified at 23° ±5°C: ±5% (1.0 to 1.6 µm). Measurement accuracy linearity continuous light: 23°C, -23 dBm as reference: ±0.15 dB, (±0.45 dB for - 70 to -60 dBm). Resolution: W, W (REL) display: 0.1 to 1 %, dBm display: 0.01 dB, dB (REL) display: 0.001 dB.
