A thinfilm type image slicer device comprises a main body prism,aflat optical element,and an opticalfilm.A reflective cavity is formed between the opticalfilm and a second surface of theflat optical element;the opticalfilm has an oblique side at an angleθwith respect to a projection
direction of a light beam reflection forward direction in the reflective cavity;the light beam repeatedly passes through the oblique side in the reflection forward direction;an image spot is sliced into a plurality of sliced images with the same width;and the plurality of sliced images are linearly arranged in an arrangement direction perpendicular to the slicing direction;and chief rays of the light beam corre sponding to each sliced image are parallel to each other.An operating system includes a pre-optical system,the thinfilm type image slicer device and a subsequent optical system.
