ABSTRACT:
A raster scanner is disclosed which utilizes a rotatable glass plate for compensating for scan line bow. The rotatable glass plate provides an adjustment mechanism which can shift a collimated light beam up or down in the sagittal plane to align the center ray of the light beam with the optical axis of the imaging lens of post polygon optics. When the center ray of the light beam passes over the optical axis of the imaging lens of the post polygon optic, the bow will be reduced substantially.
