Scanning optical apparatus |
摘要 |
In a scanning optical apparatus, a third optical element is configured such that a first optical axis defined as an optical axis of an incident-side lens surface of the third optical element is inclined in a main scanning plane with respect to a normal line extending from a scanning center on a target surface to be scanned and an intersection point between the first optical axis and the incident-side lens surface is shifted with respect to the normal line, and that a second optical axis defined as an optical axis of an emission-side lens surface is inclined in the main scanning plane with respect to the first optical axis and an intersection point between the second optical axis and the emission-side lens surface is shifted with respect to the first optical axis.
