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.

Claims

1. A gun having sights, the sights comprising a Galilean telescope and a target sight, the telescope having an outer diameter of less than about 16 mm. and being adapted to be spaced from a user'"'"'s eye to sight and provide a magnified image of an object past the target sight.

2. A gun as claimed in claim 1 wherein the telescope has a length of less than about 78 mm.

3. A gun having sights, the sights comprising a Galilean telescope and a target sight, the telescope being adapted to be spaced from a user'"'"'s eye to sight and provide a magnified image of an object past the target sight and to provide a field of view within the range of about 2°

to 7°

.

4. A gun as claimed in claim 3 wherein the telescope is adapted to provide a field of view of about 4°

.

5. A gun having sights, the sights comprising a Galilean telescope and a target sight, the telescope having an internal diameter of less than about 13 mm. and being adapted to be spaced from a user'"'"'s eye to sight and provide a magnified image of an object past the target sight.
