The Keysight 81010BL is an optical lens accessory engineered to reduce beam size on the detector in Keysight optical test systems. Installed between an optical head and fiber connector adapter, it enhances measurement accuracy across multiple wavelengths and fiber types. This compact lens module supports single-mode fiber at 1300 nm and 1550 nm, as well as multimode fiber at 850 nm, making it suitable for telecommunications, data communications, and precision optical characterization work.

– Compatibility & Integration
The 81010BL integrates with Keysight 815xxx and 816xxx series optical heads. Connection occurs through compatible fiber connector adapters in the 81000xx and 81001xx series, which support both 5 mm and 3 mm optical head configurations. Connector adapter selection determines the specific interface type (FC, SC, LC, ST, E-2000) for the test setup.
