Abstract
PURPOSE:To obtain a wavelength varying filter capable of choosing arbitrary wavelength at a low cost by putting an optically active substance whose angle of rotation depends n wavelength between two polarizing plates and setting at least one of the plates freely rotatably. CONSTITUTION:An optically active substance 14 is put between a polarizer 13 and an analyzer 15, and one of the polarizer 13 and the analyzer 15 is made rotatable. Light converted into linear polarization through the polarizer 13 is subjected to the rotation of the polarizing plane dependent on wavelength. Accordingly, by properly regulating the angle of the analyzer 15 to the polarizer 13, light of required wavelength can be taken out.
