Abstract:
An optical scanner assembly for producing an image on imaging material positioned on an internal surface of a curved film platen, the scanner assembly comprising:a light source for producing a light beam representative of the image to be produced on the imaging material, the light beam exiting the light source along a beam axis; anda reflective system rotatable about a rotation axis substantially coincident with the beam axis, the reflective system including:a scan optic, the scan optic including:a first reflective surface for receiving the light beam from the light source and reflecting the light beam; anda second reflective surface for receiving the light beam reflected from the first reflective surface and reflecting the light beam toward the imaging material on the internal surface of the curved film platen;a lens device for focusing the light beam onto the imaging material to produce the image thereon; anda further lens device that is stationary with respect to the rotatable reflective system, the further lens device receiving the light beam focused by the lens device, the further lens device further focusing the light beam onto the imaging material to produce the image thereon.
