Title: Scanning optical system
Inventor: YAMAGUCHI KATSUMI
IPC: G02B27/00
Filed: 1988-08-01
Abstract: PURPOSE:To increase the utilization efficiency of light by specifying the focal length in the main scanning plane of the scanning optical system and the distance between a saddle type troidal surface and a scanned surface on an optical axis. CONSTITUTION:The scanning optical system is arranged between an optical deflecting device and the scanned surface 7. A saddle type troidal lens 6 has a function which images an eccentric light beam on the scanned surface 7 and also hold the deflection start point of the light beam and scanned surface 7 almost in conjugation relation about a subscanning direction and includes the saddle type troidal surface increasing in radius of curvature of subscanning section with the distance from the optical axis as a convex lens surface. Then an inequality I holds, where fM is the focal length in the main scanning plane of the scanning optical system and (d) is the distance between the saddle type troidal surface and scanned surface 7. Consequently, the field curvature is compensated excellently and the saddle type troidal surface is installed at a distance from the scanned surface, so the high light utilization efficiency is obtained.
