ABSTRACT:
An optical beam scanning system which is employed as an optical scanning means for writing or reading information with a laser beam includes a lens disposed in front of a light deflector with respect to the path of travel of the laser beam. The lens has an optical axis normal to the axis of rotation or angular movement of the light deflector. The lens is arranged such that the laser beam will be applied thereto parallel to the optial axis thereof and at a suitable lens height thereon. The laser beam that has reached the light deflector through the lens is reflected as a scanning light beam as the light deflector rotates or is angularly moved.
