Binocular

An imaging optical device, in particular binoculars or a telescope, comprises, in addition to a casing, an optical system with at least two optical components, the distance of which relative to one another is adjustable for focus setting of the optical system. This adjustment is effected by an adjusting device, which is coupled with at least one of the two components. The position of the optical components relative to each other is detected and, by the aid of a processor, converted into a focal length of the optical system and then outputted as a focal length via an output device. In this way, the distance of an object sighted by the optical device can be determined conveniently.

A cup for an eyepiece of an optical observation instrument, comprises a peripheral wall which includes an eyepiece-connecting section for connection of the cup to an eyepiece, a transition section which adjoins the eyepiece-connecting section, a light-protecting attachment which, by way of a sectional part of the transition section, is joined to a side of the transition section that is turned away from the eyepiece-connecting section; a sight hole which is laterally defined by the peripheral wall; the peripheral wall being movable into a first, non-folded end position for someone who does not wear spectacles for preclusion of any incidence of stray light upon an eyepiece lens, and into a second, folded end position for spectacle wearers; and into a third stable position of ventilation, located between the first and the second end position, for someone not wearing spectacles.

Binoculars, telescope, or the like

A pair of binoculars, a telescope or the like, comprising a protective lens cap articulated to the front of the lens, is characterized in that a pivot joint arrangement is formed between an edge of the lens and the protective lens cap, in use having a substantially horizontal pivot axis and a substantially vertical pivot axis.

An image-forming device, especially an optical magnifying device, e.g., binoculars or a telescope, has an image influencing optical component, more specifically an eyepiece. The same is held by means of a holding device in such a way that the optical component is axially displaceable along the optical axis of the image-forming device. The holding device comprises a component holding element that is attached to and cannot move relative to the optical component, said component holding element having an adjustment marking, e.g., a dial with a plurality of individual markings reflecting the current axial position of the optical component. The holding device additionally has a marking member to accentuate at least one individual marking on the adjustment marking. With the aid of the marking member the axial position of the optical component can be marked prior to an axial readjustment of the same so that the axial readjustment can easily be reversed. This simplifies adjusting the image-forming device to the optical requirements of different users.
