The Keysight Beam Manipulator family of products (N1203C, N1204C, N1207C and N1206T) precisely bend or translate a laser beam to achieve sub-nanometer measurements. They align laser beams quickly and easily in order to reduce measurement errors. These products are usually used in combination to provide precise, independent, stable control over beam translation and angle. The precise bending and translating results in a properly aligned laser beam, minimizes Abbé and cosine errors and ensures maximum angular measurement range.
The N1203C Precision Beam Translator, described on this page, contains a refracting window at the center of a metal ball inside a precision optical mount. The translator precisely moves the outgoing beam parallel to the incoming beam without changing the angle. It is the component used primarily to reduce Abbé errors.
The N1204C and N1207C Precision Beam Benders contain a mirror at the center of a metal ball inside a precision optical mount. The benders precisely angle the beam, with a large degree of freedom around 90 degrees, without translating the beam. These components are used primarily to reduce cosine errors.
The N1204C bends the beam horizontally: Precision Horizontal Beam Bender
The N1207C bends the beam vertically: Precision Vertical Beam Bender
