Turning Mirror
10769A
Plane Mirror
The 10769A is ideal for use in laser measurement and calibration applications. In the calibration of slant bed lathes, for example, the beam steering mirror deflects the beam from the laser head upward, through the interferometer, along the lathe's cross slide. One or more mirrors can also create a path from a laser head to an interferometer located in an otherwise inaccessible position, as in the case of a milling machine with a table that moves in only one axis.

Three Axis Interferometer
10735A
Differential Interferometer
The Keysight 10735A 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:

High Stability Plane Mirror Interferometer
10706B
Angular Interferometer
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. This thermally stable optic, an exact functional replacement for the 10706A Plane Mirror Interferometer, reduces thermal measurement drift to 1/12 the value typically achieved by conventional plane mirror interferometers. The unique contribution of the 10706B is its tolerance of angular misalignment of the plane mirror reflector. The 10706A can accept a range of measurement mirror angular alignment changes.
