The HP Agilent Keysight 81010BL is an optical lens designed to enhance signal coupling efficiency in fiber optic test and measurement systems. It reduces beam size on the detector and supports both single-mode fiber at 1300nm and 1550nm wavelengths and multimode fiber at 850nm. The lens mounts between the optical head and fiber connector adapter, interfacing with 815xxx and 816xxx series optical heads including the 81521B and 81525A models.
