81521B AGILENT POWER METER OPTICAL HEAD

SOLD WITH 81000FA FC FIBER ADAPTER - TESTED AGAINST IQ - 1502 CALIBRATION POWER METER

SERIAL NUMBER - 2933605320


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.
