One Axis Differential Interferometer
10719A
-
The Keysight 10719A One Axis Differential Interferometer makes either a differential linear or angular measurement for use in single and multiple axis applications. The linear measurement gauges the displacement between two objects, such as a stage and an optical column or inspection tool. The 10719A also measures either pitch or roll. An angle is measured when both reference and measurement beams measure to the same mirror. The 10721A provides high immunity to unwanted interferometer displacement, such as thermal expansion. It is a modular, compact design with monolithic optics for maximized mechanical stability. Use of a small 3 mm beam helps decrease Abb offset error.

Single-Port Tunable Laser System Source
N7711A
-
The Keysight N7711A and N7714A tunable lasers are single-port and four-port sources, available with C-band or L-band wavelength coverage. The narrow linewidth and offset grid fine-tuning capability make them ideal sources for realistic loading of the latest transmission systems. All models can reach any wavelength point within their specified wavelength range just like all other Keysight tunable lasers. In this mode, code compatibility with existing test setups based on Keysight's range of full-size and compact tunable lasers is a great asset. In system loading applications, it may be preferable to grid-tune the lasers like system transmitters, simply by changing the channel index. The channel grid is adjustable to standard ITU-T grid spacing like 50 GHz, and to arbitrary grids. Likewise, the zero frequency (base channel) of the chosen grid is adjustable. A 12 GHz fine-tuning range allows de-tuning the frequency.

Fixed Laser Source Module
-
Keysight offers a broad choice of fixed laser sources, which are available as single-wavelength and dual-wavelength modules as part of the Keysight Lightwave Solution Platform. The Keysight 8165xA Fabry-Perot laser sources can be used in conjunction with optical power meter modules for insertion loss, optical return loss and PDL measurement of broadband components and fiber. The Keysight 81663A Distributed Feedback Laser Sources are best suited for amplifier test and WDM system test applications. Keysight covers PON and common WDM wavelengths with its 81663A Distributed Feedback (DFB) laser source modules. The precise tunability around ITU-grid center wavelength gives you the flexibility to match test setups to the latest requirements of the DWDM-system. The fine-tuning allows to shift the center wavelength from one DWDM transmission channel to the adjacent channel in dense WDM systems. The built-in isolator ensures highest laser stability, even when reflections are present in the optical path.

-
The Keysight 10736A Three Axis Interferometer is used in multiple axis applications where linear and angular control of the stage is required. It combines in a single package the functionality of an optical bench with multiple beam benders, beam splitters, and three interferometers. The interferometers split an incoming laser beam into three beams to measure linear distance, pitch and yaw, or linear distance, roll and yaw. Three linear measurements provide the basis for calculating two angular measurements. The inherent beam parallelism ensures that there is essentially no cosine error between the three measurements and also ensures angle accuracy for pitch and yaw measurements.
