This abstract first appeared for US patent application 18756478 titled 'SCANNING OPTICAL APPARATUS
Original Abstract Submitted
A scanning optical apparatus is configured such that a first entrance surface that is an entrance surface of the first scanning lens is symmetrical in the main scanning direction, a first exit surface that is an exit surface of the first scanning lens is symmetrical in the main scanning direction, a second entrance surface that is an entrance surface of the second scanning lens is symmetrical in the main scanning direction, a second exit surface that is an exit surface of the second scanning lens is symmetrical in the main scanning direction, an optical axis of the second exit surface is shifted with respect to an optical axis of the second entrance surface in the main scanning direction, and an optical axis of the second exit surface is tilted around an axis that is perpendicular to both the main scanning direction and the optical axis of the second exit surface.
