Abstract
Polarized light which is emitted from an optical fiber becomes circular polarized light by passing through a first quarter wave plate. The circular polarized light which has entered a second quarter wave plate is converted into nearly linear polarized light which has S polarization. P polarization components are removed from the nearly linear polarized light by a polarizer, but the polarizer is not always necessary. The optical axis of the polarizer is set to be a direction which allows transmitting of S polarized light. The light that has passed through the polarizer is separated into diffracted lights by a diffraction grating, and is used as the structured illumination light.
