Abstract

The binocular telescope has in each barrel a focusing member (internal focusing) which is joined to a support guided on a guide rod. When a control knob is actuated, this support is displaced axially by means of a transmission bar. A driving pin, which engages into the focusing member, is integrally formed on the support for this purpose. A spring which interacts with the driving pin and acts upon the focusing member effects tilt-free guidance and prevents radial play, even with short guide lengths of the focusing member.
