Abstract
A handheld optical sighting device having a sighting means for direct forward observation and reflective surfaces that enable images of two objects, one directly ahead of and one directly to the rear of an observer to coincide when the device is aligned with and between the two objects. The device includes two reflective surfaces for reflecting light rays from the rear object by 180 degrees.
Claims7
A handheld optical sighting device which permits simultaneous observation of two objects, one directly forward of an observer and the other directly to the rear of the observer along parallel paths comprising, sighting means and reflective surfaces enabling images of the two objects to substantially coincide when the sighting device is in alignment with and between the two objects located forward of and to the rear of the sighting device, respectively, wherein the sighting means for the forward object comprises means for directly receiving the light rays coming from said forward object so that these rays impinge an the observer's eye without being reflected, whilst light rays coming from the rear object are subjected to a 180.degree. reflection resulting from two successive reflections of 90.degree., caused by said reflective surfaces before entering into the said sighting means.
