Abstract
A laser microfilm printer ( ) having a telecentric F-theta scan lens ( ) with optical resolution for image pixel sizes 1-5 microns for writing on an image-receiving medium ( ) comprises a polygon reflector. A laser beam incident on the polygon reflector, has a diameter as measured at the 1/e intensity value, which is at least 1.4 times a width of a polygon facet ( ) in a scan section of the laser microfilm printer ( ). The polygon facet ( ), at center of scan position, is in a substantially optically conjugate relationship with the image-receiving medium ( ) in a cross-scan section of the laser beam ( ). The cross-scan section of the F-theta lens ( ) has an absolute value of optical magnification of 0.25 to 0.5 as measured from the facet ( ) to the image-receiving medium ( ).
