ABSTRACT:
A far-optical device comprising a reversal system and an adjustable optical magnification means with more than fourfold magnification, wherein the far-optical device has an optical beam deflection means which at all magnifications ensures a subjective field of view of the far-optical device of at least 22° at least for light of a wavelength of about 550 nm.
