The Agilent/Keysight E1834J is a 67% beam splitter mounted in a precision horizontal configuration for laser interferometer measurement systems. It routes and splits incident laser beams into transmitted and reflected outputs with high pointing stability, using 416 stainless steel construction and flexure-foot mounting to maintain optical alignment across operating temperature ranges.
