  • Optical device including an optical lens and reflectors with reflections in series
    Patent number: 5039215
    Abstract: The optical device is preferably used for a telescope, and has a pair of reflectors attached to a front end of a cylindrical section, so that objects can be searched or traced. The optical device has a first reflector provided in front of an object lens, which is provided at a front end of a rotatable cylindrical section. The first reflector reflects the light in a direction perpendicular to the optical axis of the object lens. A second reflector provided is close to the first reflector and the second reflector reflects the reflected light from the first reflector in parallel to the optical axis of the object lens. The first reflector can be rotated in a plane which is positioned between the first reflector and the second reflector and which is perpendicular to the optical axis of the object lens, and the second reflector can be independently rotated on the optical axis thereof.
