Three Axis Interferometer
10736A
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. Other characteristics include:

The Keysight 10715A Differential Interferometer performs differential measurements between the supplied reference mirror and a measurement plane mirror. It provides exceptional long term stability. The 10715A minimizes dead path, and, because the entire optical path through the interferometer is common mode, it eliminates thermal drift in measurements. The resolution of the measurement is twice that of a linear or single-beam interferometer.

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.

Interferometer
S100|HR
CNC polishing puts new demands on metrology tools. Many of these optics are aspheric with tight tolerances. The new machines can produce almost any surface and require a new level of metrology to provide feedback to the polishing process. This just cannot be done with outdated interferometers designed over 30 years ago. The S100|HR has the performance it takes, without breaking the bank. Measure 10X higher fringe densities to enable final figuring to begin sooner, saving you time and money. Plus measure these high density fringes 5X more accurately to enable large polishing corrections that converge quickly to final figure, including aspheres.

40Gb/s DQPSK Receiver
The integrated DQPSK receiver incorporates an optical phase demodulator (delay-line interferometer or DLI) with 2 pairs of balanced photo-diodes and 2 linear TIAs into a single butterfly package. Compared with the currently available discrete solution in which a separate DLI and a separate receiver are used, the integrated DQPSK receiver eliminates labor intensive fiber routing and coupling (between the DLI and the balanced receiver) as well as the skew control. Moreover, the integrated DQPSK receiver offers a smaller footprint suitable for today’s demanding high speed transponder applications.

High Stability Plane Mirror Interferometer
10706B
The Keysight 10706B High Stability Plane Mirror Interferometer is a dual pass interferometer used for multiple axis applications such as X-Y stages where the measurement mirror may move perpendicular to the measurement axis.
