Abstract
The invention aims to provide binoculars suitable to be used in a theater or a sports stadium, which can provide a wide and bright field of view on one hand, and which are compact and lightweight with improved portability and maneuverability on the other hand. Inverse reflection of an image is achieved by providing optical systems of inverse reflection, each comprising a pair of specular reflectors opposed to each other on an object side and an eyepiece side, respectively, so that an optical axis of light exiting the optical system of inverse reflection on the eyepiece side extends in parallel with an optical axis of light entering the optical system of inverse reflection on the object side, and one or more object lens(es) is or are placed on one or more path(s) selected from optical paths of reflection from respective specular reflectors forming the optical systems of inverse reflection.
