【Abstract】 The general property of an assemble of a half wave plate and polarizers is discussed by Jones algorithm. An expression for attenuation precision of the assemble is given. Finally, the experimental result of transmissivity property of an assemble, consisting of a 45 mm quartz half wave plate and two polarizers, is reported.更多还原
