Abstract: An improved optical composing stage is disclosed which has a variable-area aperture including a plurality of aperture-defining blades which are angled at their leading edges so that light incident thereon from a light source is directed out of the field of view of a recording medium, whereby image flaring due to edge reflection is prevented. The optical composing stage further comprises a composite structure made up of parallel plates. Convenient horizontal angular alignment adjustment of the plates is obtained in that a locating pin on a lower plate extends upward into a locating groove formed in the underside of a rotatable skew adjustment knob. The stage further includes a plurality of spaced object planes which provide for simultaneous imaging of a plurality of negatives, each separately controllable as to whether it is in focus or out of focus.
