Abstract
A prism block is provided at least one notch to propagate in the light flux in air, on an optical path from entrance of a light flux via a first portion of the prism block to exit of the light flux via a second portion of the prism block. The notch is configured such that the light flux exiting from inside of the prism block via a first interface of the notch between the prism block and the air re-enters the prism block via a second interface between the air and the prism block, the second interface facing the first interface.
