These two screws are beamsplitter "blockers". Then slide metal wing side DOWN. One of the biggest challenges for modeling such a system is that multiple ray paths cannot be simultaneously traced in Sequential Mode. The uniform ty error ( − ) ⁄( + ) is < 2. Besides, the power in the highest unwanted diffraA diffractive Beam Splitter, or Multispot (MS), is a grating-like periodic diffractive optical element (DOE) used to split a single laser beam into several beams, called diffraction orders, in a predefined configuration. This document describes this product line, as well as general operation guidel into two output beams t beams of equal power.
