Abstract: PURPOSE: A phase transition interferometer using multi-wavelength is provided to measure the information of two phases by using two wavelengths, thereby enlarging a measurement region and measuring a structure of a size less than a nano unit rapidly. CONSTITUTION: A phase transition interferometer using multi-wavelength comprises a laser oscillating unit(100), a mode mixer unit(200), a first beam splitter(350), a Mirau object lens, a wavelength divider, a pixel rated CCD camera(500), and a PC unit(600). The laser oscillating unit oscillates a plurality of lasers with different wavelengths. The mode mixer unit makes the coherence of the wavelengths of the laser oscillated by the laser oscillating unit shorter. The first beam splitter transmits and reflects the lasers penetrated through a lens(310) and a line polarizer(320) after coming out from the mode mixer. The Mirau object lens measures a target object(360) with the lasers reflected by the first beam splitter. The wavelength divider divides the lasers penetrated through a quarter wavelength board(340) into a plurality of wavelengths.
