Do 1-to-2 beam splitters have the same beam splitting intensity

The beamsplitter acts to divide the light's intensity in a given ratio over a range of wavelengths, generating two beams with the same spectral composition, if not the same intensity. These exiting beams are differentiated by either their optical power (non-polarizing) or polarization states (polarizing). Non-polarizing beamsplitters are specified by their splitting ratio, i. It is a crucial part of many optical experimental and measurement systems, such as interferometers, also finding widespread application in fibre optic telecommunications. [pdf]
