  • Optical splitter splits a beam into two at 95 accuracy

    Optical splitter splits a beam into two at 95 accuracy

    A 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. Beam splitters are critical for managing optical power flow in a wide range of setups. Selecting the right component involves navigating trade-offs between power handling, polarization sensitivity, chromatic dispersion, and mechanical stability. This is common in interferometry, imaging, and for feedback loops in optical systems.
