Abstract: PURPOSE: A dual-pass etalon spectrometer is provided to generate a precise fringe data able to measure band widths having a precision required for microlithography with relation to delta lambda FWHM and delta lambda 95%. CONSTITUTION: In a dual-pass etalon spectrometer, an optical scattering system(34) makes laser beams(16) facing toward a plurality of directions for generating scattered beams, and spectrum components of the scattered beams are divided by an angle to be permeated via the etalon(25). A reverse reflection mirror(38) reflects the permeated light beam components reversely via the etalon. The twice permeated spectrum components is focused on an optical detector(44) formed of an optical diode array by a lens(42) to detect a fringe pattern(49). The reverse reflection mirror is to be a hollow reverse reflection mirror.
