How to Select a Beamsplitter

Upon encountering the back surface of the substrate, a small portion of the light is reflected back along the path of the reflected beam, creating a ghost beam with a small displacement (~0.3x the thickness

Infrared Spectroscopy: Beam Splitters and Detector Physics Explained

The material you use for the beam splitter, like potassium bromide (KBr) or cesium iodide (CsI), sets the spectral range you can actually use. Beam splitters need to keep transmission and

Beam Splitter

A beam splitter is then used to pick off a small portion (2–10%) of the beam to sample the profile before passing the energy across two additional beam-turning mirrors and into a focusing lens.
