ABSTRACT:
A viewing field splitter particularly useful for simultaneously viewing two sides of an object for alignment purposes in which the two fields are obtained from microscopes mounted to pivot about the center of an arc which is illuminated. The microscope outputs are inputs to periscopes with one mirror from each periscope located on the axis of the pivot such that there is no rotation of the image and path lengths from each optical element to the point of combination of the fields are equal.
