Keysight 81620C Silicon Optical head
Exfo InGaAs and integrating cavity Head
The HP 81525A is an optical head that connects to the 81533A or 81533B which is a plug-in module that fits the 8153A and 8163 and 8166 Agilent/HP series mainframe. The 81525A optical head is made of a 5mm InGaAs sensor element and covers the range of 800-1650nm wavelengths. Various connector interfaces are available for that head.
The HP Agilent 81525A High Power InGaAs Optical Head is designed for professionals who require high-precision optical power measurements with an extended power range. Supporting wavelengths from 800 to 1650 nm and featuring an InGaAs detector, this optical head is ideal for fiber optic testing applications requiring low polarization-dependent loss (PDL), minimal spectral ripple, and high return loss.
Equipped with a magnetic D-shape adapter, the HP Agilent 81525A provides a secure and stable setup for precise optical component measurements.
