The Agilent/Keysight 10725A is a beam splitter optic engineered for laser interferometer positioning systems. It divides incoming laser beams into two equal parts: one transmitted straight through and one deflected at 90 degrees. Designed for 9 mm or smaller beam diameters, this bare optic requires user-supplied mounting hardware and integrates into multi-axis stages to extend angular measurement range.
