  Einstellen für photographische Apparate. 



   Gegenstand vorliegender Erfindung ist eine weitere Verbesserung des durch Österr. Pat. Nr. 93599 unter Schutz gestellten Einstellers. 



   Die im Stammpatent vorgesehene, spiegelnd hinterkleidete Mattscheibe kann zur   Verbesserung   der Helligkeit und Verdeutlichung des Bildes durch einen Spiegel ersetzt werden. Das von der Linse entworfene Bild wird dann entweder in die Spiegelebene oder in eine besondere Bildebene fallen. Es kann aber auch die spiegelnd hinterkleidete Linse mit einem Prisma zusammen verwendet werden, dessen eine Fläche

   Das Einstellerbild wird durch eine Lupe dem Auge sichtbar gemacht, wobei es vergrössert wird. was die Scharfeinstellung erheblich begünstigt. 



   In Fig.   1#6   sind   Ausfuhrungsbeispiele   des Erfindungsgegenstandes schematisch dargestellt. Fig. 1 zeigt eine bei 1a mit Spiegel hinterkleidete Linse 1 und einen in   ihrer Achse liegenden Spiegel.'2 mit zentraler

  Setting for photographic apparatus.



   The present invention is a further improvement of the Österr. Pat. No. 93599 adjuster placed under protection.



   The reflective backing screen provided in the parent patent can be replaced by a mirror to improve the brightness and clarify the image. The image created by the lens will then fall either into the mirror plane or into a particular image plane. However, the reflective rear lens can also be used together with a prism, one surface of which

 of the beam path in a special image plane.



   The setting image is made visible to the eye through a magnifying glass, whereby it is enlarged. which significantly favors focusing.



   In Fig. 1 # 6 exemplary embodiments of the subject invention are shown schematically. 1 shows a lens 1 covered with a mirror at 1a and a mirror located in its axis with a central
 EMI1.2
 Magnifying glass; J and a mirror 2 arranged therefrom, in the plane of which the sharp image is visible if the setting is correct.



   FIG. 3 shows the arrangement according to FIG. 2 in connection with an interposed diffusing lime 4, which serves to delimit the image.
 EMI1.3
 hang with a prism 5, one surface of which is designed as a mirror 2.



   FIG. 5 shows the connection of a lens 1, which is partially covered in a mirror-like manner at 1a, with a prism 5 with a matt screen 6.



   6 shows the connection of a lens 1 covered with a mirror 1 a, likewise with a prism 5, one surface of which is designed as a ground glass screen 6.
 EMI1.4
 in such a way that these image rays unite when focusing either in the plane of the mirror, which in this case acts like a frosted disk, or in a special image plane to form the real image.
