  • Patent number: 5052790
    Abstract: To provide for bi-level viewing through a miniature Galilean telemicroscope, the telemicroscope is mounted to a carrier such that its optic axis is angled relative to a principal optic axis defined by the carrier. The carrier may be a spectacle lens, an adaptor to be pressure fit to the rear portion of the aiming mechanism or a gun, or an adaptor to be coupled to an optical instrument. The miniature scope may also be used as the principal sight aperture. Where the optical instrument is a larger telescope, an additional cross hair allows for alignment of the telemicroscope. Fibers extending inwardly from the inner surface of the telemicroscope barrel minimize internal light reflection. The telemicroscope barrel is formed of threaded-like coupled portions which may be rotated relative to each other for focusing.
