HIGH-RESOLUTION OPTICAL SYSTEM OF UNIDIMENSIONAL QUASI-LINEAR SCANNING WITH LASER BEAM Russian patent published in 2004 - IPC

FIELD: optical instrumentation. SUBSTANCE: invention can be used for design of optical scanning systems, for instance, optical systems of laser printers. Given high-resolution optical system has laser, focusing element, multifaceted mirror drum mounted for rotation and astigmatic singlet with aspherical surfaces placed in sequence along optical axis Z. Surface equation of singlet has certain type. EFFECT: reduced cost due to diminished time for design and expanded allowances for manufacture by diminished waviness of surfaces of singlet, decreased amount of rejects. 3 cl, 1 dwg
