Peculiar properties of polarized transmission spectrums of crystal plates

The optical system containing polarizer, analyzer and two crystalline plates, which are cut parallel to the optic axis is considered. The transmission spectrums of two planar - cross crystalline plates made from niobate of lithium crystal are calculated. The possibility of controlling the spectrum at different combinations of plates' orientation relatively to the polarizer's transmission plate and also at rotation of the analyzer is shown.© (2007) COPYRIGHT SPIE--The International Society for Optical Engineering.
