Abstract

The adaptor is provided to connect a microscope (5) and a video camera or a reflex camera. The adaptor has a connector on its lower side which connects with the tubular head of the microscope. On its upper side, the adaptor has an outer thread corresponding to the filter thread of the video camera. The adaptor can be connected to the housing (1) of the camera by an adaptor ring (3). An auxiliary lens of one or more lenses is mounted in the adaptor. The optical effect of the auxiliary lens is equal to that of a concave lens.

Description

Die Erfindung betrifft einen Adapter, dessen Hilfsobjektiv nicht wie bisher die Wirkung einer Sammellinse, sondern den einer Zerstreuungslinse hat. Dabei sind nicht nur bikonkave, sondern auch andere Linsenformen möglich. Als optimale Linsenstärke hat sich der Wert von - 10 Dptr. erwiesen, jedoch sind durchaus auch andere Werte im Minusbereich denkbar.The invention relates to an adapter, the auxiliary lens of which is not as before the effect of a converging lens, but one Has diverging lens. These are not just biconcave, but other lens shapes are also possible. As the optimal lens power the value of - 10 dptr. proved, however, are also other values in the minus range conceivable.

Gegenüber bisheriger Video- und Photoadapter im mikroskopischen Bereich hat die Erfindung den wesentlichen Vorteil eines sehr kurzen Adapters mit damit verbundener Stabilität und Handlich­ keit der Vorrichtung.Compared to previous video and photo adapters in microscopic The invention has the essential advantage of a very range short adapter with the associated stability and manageability speed of the device.

Die wesentlichen Merkmale der Erfindung wurden bereits in der vorausgegangenen Patentanmeldung DE 43 00 070 C1 beschrieben. Als darüber hinausgehend haben sich folgende Gesichtspunkte ergeben:The essential features of the invention were already in the previous patent application DE 43 00 070 C1 described. The following aspects have to be considered further result in:

  • 1) Das Hilfsobjektiv muß nicht eine bikonkave Linse sein, es kann beispielsweise auch ein konkavkonvexes Brillenglas sein.1) The auxiliary lens does not have to be a biconcave lens, it can for example, a concave-convex lens.
  • 2) Das Hilfsobjektiv kann auch aus mehreren Linsen, z. B. zur Ver­ besserung der Abbildungsqualität bestehen.2) The auxiliary lens can also consist of several lenses, e.g. B. Ver there is an improvement in the image quality.
  • 3) Je nach zu adaptierenden Geräten können auch Abweichungen vom Wert - 10 Dptr. möglich sein, allerdings im Bereich einer Zer­ streuungslinse3) Depending on the devices to be adapted, deviations from the Value - 10 Dptr. Be possible, but in the range of a cer scattering lens
  • 4) Zusätzlich zur Anwendung im Videobereich ergibt sich die An­ wendung im photographischen Bereich. Es ist von Vorteil, wenn ein Mikroskopiker mit dem Mikrocam- Adapter nicht nur Videoaufnahmen, sondern auch Photographien machen kann. Dadurch erübrigt sich die Anschaffung eines Photoadapters.4) In addition to the application in the video area, the An results application in the photographic field. It is beneficial if one Microscopists with the microcam adapter not only video recordings, but can also take photographs. This makes it unnecessary the purchase of a photo adapter.

Fig. Zeigt SLR- Kamera, verbunden mit dem Mikroskop. Das Spiegelreflexkameragehäuse (1) kann direkt auf den Mikrocam- Adapter (4) gesetzt werden. Dabei ergibt sich ein Herabsetzen des Vergrößerungsmaßstabes im Vergleich zum beobachteten mikroskopi­ schen Bild. Um einen normalen Abbildungsmaßstab zu erreichen, kann zwischen Mikrocam- Adapter und Kameragehäuse ein Zwischenring (2) beliebiger Länge gegeben werden. Einen normalen Abbildungsmaßstab erreicht man jedoch bei einer Länge von 7-10 cm. Beim Wechsel der Mikroskopobjektive muß nachfokussiert werden. Der Zwischen­ ring muß kameraseits den entsprechenden Bajonettanschluß und zum Mikrocam- Adapter hin das entsprechende Innengewinde haben. Auch ist aus Kostengründen bei vorhandenen Makro- Zwischenringen, im Zubehörhandel erhältlich, nur noch zum Mikrocam- Adapter ein Adapterring (3) nötig, der auf der Oberseite das Kamerabajonett und auf der Unterseite das passende Innengewinde hat.Fig. Shows SLR camera connected to the microscope. The SLR camera housing ( 1 ) can be placed directly on the microcam adapter ( 4 ). This results in a reduction in the magnification scale compared to the observed microscopic image. In order to achieve a normal imaging scale, an intermediate ring ( 2 ) of any length can be placed between the microcam adapter and the camera housing. A normal image scale is achieved with a length of 7-10 cm. When changing the microscope objectives, refocusing is required. The intermediate ring must have the corresponding bayonet connection on the camera side and the corresponding internal thread towards the microcam adapter. For cost reasons, existing macro intermediate rings, available in the accessories trade, only need an adapter ring ( 3 ) for the microcam adapter, which has the camera bayonet on the top and the matching internal thread on the bottom.
