【Abstract】 Optical flux is an important parameter of polarization interference spectrometer. On nonideal condition, the weakening parameter for incident intensity with Wollaston splitter and polarizer and the optical flux of spectrometer based on double Wollaston prisms is discussed, and the accurate optical flux expression is presented. The optical flux with maximum modulation degree is given and compared with flux on ideal condition.更多还原
