The Keysight 5529 A is a laser interferometer. The Keysight 5529 A is used for precision optical measurements.[1][2]
What it is
The Keysight 5529 A is a laser interferometer classified under precision optics equipment.[1]
How it works
General reference — not yet source-verifiedThe Keysight 5529 A is a laser interferometer that measures displacement with high accuracy by splitting a laser beam into two paths, recombining them, and analyzing the resulting interference pattern.
Where it fits in the process flow
General reference — not yet source-verifiedLaser interferometers of this class are used in semiconductor fabrication for precise positioning and alignment of stages, masks, and wafers during lithography, metrology, and inspection steps.
