Description of Keysight (Agilent/HP) 81521B

Categories: Sensors, Optical Sensors

Manufacturer: Keysight Technologies (Agilent HP)

Model: 81521B

Condition: Used

Seller: Rosenkranz Elektronik

Keysight (Agilent/HP) 81521B Optical Sensor, 900 - 1700 nm

Product specifications of Keysight (Agilent/HP) 81521B (From Used-Line T&M Specifications)

  • Launch Date Jan-2049
  • Alternative 81623B Germanium or Silicon Optical Power Head
  • Status Discontinued by Manufacturer

The HP 81521B covers almost all common applications in the wavelength range from 850 to 1700nm. The optical head features a non-volatile memory for storage of wavelengths other than 1300 nm. Simple entry of the wavelength at the power meter ensures accurate measurements.

The 81521B can be used for high precision power measurements in both parallel-beam and connectorized applications.

With an attenuating lens adapter, such as the 81230FL, it can be used to perform calibrated absolute power measurements on unpackaged laser chips or LED chips. With the 81000BA/CA bare-fiber adapter, it can interface to a fiber pigtail with a typical repeatability of <0.02 dB.

  • Wavelength range: 850 to 1700 nm
  • Sensor element: Cooled Ge PIN diode
  • Sensor diameter: 5 mm
  • Applicable fiber type: Parallel beam, 9/125 µm - 100/140 µm, NA ≤0.3
  • Maximum power density: 10 mW/mm
  • Measurement range: +3 to -80 dBm
  • Noise: <50 pW (1200-1600 nm) 
  • Uncertainty: ±2.2% (at reference conditions, 1000 - 1650 nm)
