The Agilent/Keysight 55280A is a linear measurement kit designed for high-precision metrology applications. It is a component of the Keysight 5530 Laser Calibration System and is used to measure linear distance (displacement) and velocity. The 55280A kit includes optical equipment, such as the Keysight 10766A Linear Interferometer and two Keysight 10767A Linear Retroreflectors, along with mounting hardware and a transit case. This system measures the change in distance between the interferometer and the retroreflector, enabling accurate calibration of positioning accuracy for numerically-controlled machine tools and coordinate measuring machines. It can also serve as a standard for calibrating length standards due to its high accuracy and resolution.
