Abstract
PURPOSE:To uniformize the distribution of intensity of illumination of an object to be radiated by arranging two orthogonally crossed cylindrical lenses, making the focal points of the respective lenses coincide with each other and arranging a beam scanner on the transmission path of a laser beam. CONSTITUTION:The laser beam 1a incident in a horizontal direction is condensed by the cylindrical lens 11 and turned to a vertical direction by the beam scanner, for instance, a polygon mirror 12. And it is converged on the cylindrical lens 3 which is orthogonally crossed with the lens 11. Since the focal points 4 and 13 of the lenses 3 and 11 are on the same position, the laser beam 1g becomes a small oval. And if the polygon mirror 12 is rotated, the reflected beam 1f is made to scan only circular arc ltheta by a deflection angle theta in the long axis direction of the oval. Since the long axis of the condensed beam is extremely shorter than the circular arc, that means, amplitude ltheta, the scanning beam 1g possesses the uniform distribution of intensity of illumination.
