Electro Optical Components, Inc. Quartz Optical Rotators

When plane polarized light propagates along the optic axis of quartz, it is rotated clockwise or anticlockwise depending on whether it is right or left hand quartz. The rotation is dependent on the wavelength and the distance traveled, as shown below. Specific Rotary Power: Quartz rotators can be supplied to give 90° rotation or any angle between 0-90°. They are ordered as standard components with the same aperture and mount dimensions as those shown for retardation plates but by using the suffix, QOR.
