The HP 81525A optical head 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: 800 - 1650 nm
  • Power range: +27 to -70 dBm (1250 to 1650 nm), +23 to -70 dBm (800 to 1650 nm)
  • Applicable fiber type: Parallel beam, 9/125 µm - 100/140 µm, NA ≤0.3
  • Noise: <500 pW (900-1600 nm)
  • Uncertainty: ±3% (at reference conditions, 900 - 1600 nm)
