ABSTRACT:
A high performance binocular which, by accurately seating and housing four lightweight mirrors of each telescope in a lightweight shell that almost exactly encloses its extremely short optical system, results in an optical instrument which is much smaller and approximately eight times lighter than a conventional or standard prism-type binocular having the same optical characteristics. A novel positioning of the four mirrors within each telescope shell of the binocular serves to fold the optical space within such shell so that there is minimum mirror overlap along the direction of sight, thus resulting in an instrument in which the eyepiece and objective apertures are nearly coplanar so that the eyepiece and objective barrels are collapsed toward each other with the result that they are appreciably withdrawn into the over-all confines of the telescope shells in order to produce an extremely short instrument.
