Abstract: PURPOSE:To detect the focusing state with high accuracy, by making each of plural divided luminous fluxes incident to each corresponding photodetector and then comparing the outputs delivered from the photodetectors with each other. CONSTITUTION:A beam splitting means 2 consists of a diffraction grating which is formed by connecting consecutively plural transparent members 25.
