Binoculars with open bridge design

摘要

the invention relates to a binokulares binoculars with knickbru00fccke to adapt the okularabstandes to augenweite of the user. synchronous focusing the two telescopes is accomplished by means of a differentialzahnradgetriebes which each spindeltrieb drives for each of the two telescopes.the implementation of the rotation in an axial linearverschiebung fokussierenden element of the optical system is only at the end of the spindeltriebs.
