The Keysight 10717A Wavelength Tracker tracks changes in the air's index of refraction to optically compensate for environmental changes. It uses one axis of a laser measurement system to report wavelength of light changes, not changes in position. It is used to correct displacement values reported by other measurement axes in the system, hence improving measurement accuracy. It provides a higher degree of accuracy than environmental sensors such as the 10751C and 10751D Air Sensors.

The 10717A includes an optical reference cavity (called an etalon) and a 10715A Differential Interferometer. Both are mounted on a common metal base plate and pre-aligned at the factory.
