Abstract: PURPOSE:To compensate the shear of an optical beam and to fix the center of the intensity of irradiated beams always constantly by arranging the 3rd optical system for varying one optical beams out of two in the reverse direction to the vertical variation of the optical beam. CONSTITUTION:An optical beam 6a radiated from a light source 1 is divided into two optical beams 6c, 6d by a beam splitter 2 and one optical beam 6d is passed through an image rotator 3 and irradiated to an objective irradiating surface 5 through a lens 4 together with the other optical beam 6c.
