ABSTRACT:
Disclosed is an optical scanner assembly for producing an image on imaging material positioned on an internal surface of a curved film platen. The scanner assembly includes a light source for producing a light beam representative of the image to be produced on the imaging material, a reflective system rotatable about a rotation axis, and a toric lens. The reflective system comprises a scan optic defined by a pentaprism and a cylindrical lens. A first reflective surface of the pentaprism receives the light beam from the light source and reflects the light beam to a second reflective surface of the pentaprism. The light beam is further reflected by the second reflective surface towards the imaging material through the cylindrical lens and the toric lens, which act to focus the light beam onto the imaging material to produce the image thereon. The cylindrical and toric lenses in conjunction with the pentaprism correct for wobble along the rotation axis of the reflective system caused by bearing and mechanical inaccuracies in a drive mechanism of the reflective system.
