Description

Es sind bereits Vorrichtungen zur Schärfeneinstellung von photographischen Apparaten bekannt geworden, bei denen der Leuchtfaden einer in der Bildebene angeordneten Lampe mittels der Aufnahmeoptik auf den zu photographierenden Gegenstand scharf einzustellen ist.There are already devices for adjusting the focus of photographic apparatus become known in which the filament of a lamp arranged in the image plane by means of the optical system towards the the subject to be photographed in focus.

Die Neuerung gemäß der Erfindung besteht darin, daß der Leuchtfaden h einer elektrischen Glühlampe g, der ungefähr in der Bildebene α liegt, durch eine zweite Optik d, welche in der Ebene der Aufnahmeoptik c liegt und mit der Aufnahmeoptik zwangsweise verschiebbar ist, auf den aufzunehmenden Gegenstand e projiziert wird. Die Teile sind derart angeordnet und verbunden, daß eine scharfe Abbildung des Gegenstandes e auf der Platte α erfolgt, wenn das Bild des Leuchtfadens b auf dem Gegenstand e scharf erscheint. Hierdurch ist es möglich, den Aufnahmeapparat so vorzubereiten, daß die Aufnahme nach dem Einstellen sofort erfolgen kann, und beide optische Systeme gesondert so abzublenden, wie es einerseits für die Einstellung und andererseits für die Aufnahme am günstigsten ist.The innovation according to the invention is that the filament h of an electric incandescent lamp g, which lies approximately in the image plane α , through a second optic d, which lies in the plane of the receiving optics c and is forcibly displaceable with the receiving optics, to the to be recorded Object e is projected. The parts are arranged and connected in such a way that a sharp image of the object e on the plate α occurs when the image of the filament b on the object e appears sharp. This makes it possible to prepare the recording apparatus in such a way that the recording can take place immediately after setting, and to mask both optical systems separately in such a way that it is most favorable on the one hand for the setting and on the other hand for the recording.
