The Agilent 81624A Optical Head covers the power range from +10 to –90 dBm. Thanks to the excellent accuracy, high linearity and low polarization dependent loss (PDL) best measurement results are ensured.It is especially suitable for obtaining the highest requirements in absolute accuracy, e.g. for calibration services, and also for open beam measurements. Specifications. Wavelength Range: 800 nm to 1700 nm. Power Range: +10 dBm to -90 dBm. Uncertainty (accuracy) at reference conditions: <±2.2% (1000 nm to 1650 nm). Linearity (power) at 23°C ±5°C: (CW +10 dBm to -70 dBm) <±0.02 dB ±5 pW. Power Sensor Type: InGaAs, 5 mm.
