And this paper also shows the structure and parameters of the optical system. The Xenon light of super high voltage is used as interferential source. The position of it is on the focus of the reflector of ellipsoid surface. After reflecting, its lights form a collective point . This point and objective focus of collimation lens are superposition. Though the collimation lens, the beam of light become parallel lights. Then though the Coude Reflector and radiation system of special prism, the lights become a beam of light with 3 ° emanative angle.
