Nd: YAG laser can have second and third harmonics. These three harmonics are useful in scientific community. When an optical system uses these harmonics, they need to combineseparate at the detector plane. A dichroic beamsplitter coating can be used...
Plate beam splitterPlate beam splitters are polished flat and coated glass substrates which are in general used at 45 degree in an optical system. Highly polished surface is coated with the beam splitter coating, while the other commercially...
