Back reflection of beam splitter

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

How does a beam splitter split a reflected beam?

Light reflected from the sample gets reflected ''downward'' by the beam splitter. Exactly as expected. But if that light then strikes something reflective, some light

OverviewReflection beam splittersDesignsPhase shiftClassical lossless beam splitterUse in experimentsQuantum mechanical description

Reflection beam splitters reflect parts of the incident radiation in different directions. These partial beams show exactly the same intensity. Typically, reflection beam splitters are made of metal and have a broadband spectral characteristic. Due to their compact design, beam splitters of this type are particularly easy to install in infrared detectors. At this application, the radiation enters through the aperture ope
