REFLECTION TYPE IMAGING ELEMENT AND OPTICAL SYSTEM

PROBLEM TO BE SOLVED: To provide a reflection type imaging element that can be manufactured with a simple method, and provides a high quality aerial video.SOLUTION: A reflection type imaging element 100A of the present invention includes: a light-receiving surface 2 that receives light from an object of projection 70; and a first reflection type element 10a and a second reflection type element 10b having an emission surface 4 which is parallel to the light-receiving surface 2 and from which the light from the object of projection 70 emits. When the rate of light that contributes to imaging among the light from the object of projection 70 is light amount rate, and an angle in which the light from the object of projection is made incident on the light-receiving surface at the highest light amount rate is the maximum incident angle, the maximum incident angle of the first reflection type element 10a and the maximum incident angle of the second reflection type element 10b are different from each other.
