What is the optical attenuation of a 1 2 beam splitter
A beam splitter or beamsplitter is an that splits a beam of into a transmitted and a reflected beam. It is a crucial part of many optical experimental and measurement systems, such as, also finding widespread application in. Optical splitters introduce a large attenuation, a 1:2 splitter introduces as much attenuation as an optical fiber about 10 km long (>3dB).
