Abstract
A scanning optical system is used to re-form an original image on a CCD line sensor. The optical system has an object side lens unit, a mirror and an image side lens unit. The object side lens unit condenses light from the object. The mirror is arranged between the object side lens to deflect the light having passed through the object side lens unit for scanning. An exit pupil of the object side lens unit coincide with an entrance pupil of the image side lens unit.
