Description

Die Erfindung betrifft einen Adapter zur Verbindung eines Mikroskops und eines Videoaufnahmegerätes zur Videoübertragung und -aufzeichnung mikroskopischer Bilder nach dem Oberbegriff des Patentanspruchs, wie er aus dem Hauptpatent Nummer 43 00 070 bekannt ist.The invention relates to an adapter for connecting a microscope and one Video recording device for video transmission and recording of microscopic images after the Preamble of the claim as known from main patent number 43 00 070.

Ein weiterer, aus der DE 28 48 605 A1 bekannter Mikroskopadapter erfordert eine speziell geeignete und damit kostspielige Videokamera, die nach Abschrauben des Kameraobjektivs anstelle des Okulartubus-Aufsatzes an den Tubuskopf des Mikroskops angeschlossen wird. Eine kostengünstige Anwendung dieser Methode auf handelsübliche Camcorder ist nicht möglich, da deren Objektive bei handelsüblicher Ausführung nicht abschraubbar sind.Another microscope adapter known from DE 28 48 605 A1 requires a special one suitable and therefore expensive video camera, which instead of unscrewing the camera lens of the eyepiece tube attachment is connected to the tube head of the microscope. A Inexpensive application of this method to commercially available camcorders is not possible because of it Lenses cannot be unscrewed in the commercial version.

Darüber hinaus beschreibt die US 5264928 einen Doppel-Adapter für ein Videoaufnahmegerät und eine Filmkamera, bei dem die beiden Aufnahmegeräte gleichzeitig angeschlossen werden. Dieser Doppel-Adapter enthält zwei separate Linsensysteme, eines für das Videoaufnahmegerät und eines für die Filmkamera, und ist daher teuer. Eine kostengünstige Möglichkeit, einen einzigen Adapter für beide Aufnahmegeräte bei gleichem Abbildungsmaßstab zu nutzen ist hier nicht vorgesehen.Furthermore, US 5264928 describes a double adapter for a video recording device and a film camera in which the two recording devices are connected at the same time. This Double adapter contains two separate lens systems, one for the video recording device and one for the film camera, and is therefore expensive. An inexpensive way to have a single adapter for both It is not intended to use recording devices with the same image scale.

Der Erfindung liegt die Aufgabe zugrunde, den Gegenstand der Hauptanmeldung dahingehend weiter zu verbessern, daß ein kostengünstiger Austausch des Videoaufnahmegerätes gegen eine Spiegelreflexkamera möglich ist.The invention has for its object the subject of the main application further improve that an inexpensive replacement of the video recording device for a SLR camera is possible.

Diese Aufgabe wird durch die kennzeichnende Merkmalskombination des Patentanspruchs gelöst.This object is achieved by the characteristic combination of features of the claim solved.

Gegenüber bisherigen Video- und Photo-Adaptern im mikroskopischen Bereich hat der erfindungsgemäße Adapter den Vorteil kurzer und handlicher Abmessungen mit einer damit verbundenen Stabilität. Wesentliche Merkmale der Erfindung wurden bereits in der vorausgegangenen und zwischenzeitlich erteilte Hauptanmeldung P 43 00 070.3-31 beschrieben. Darüber hinaus haben sich folgende Gesichtspunkte ergeben:Compared to previous video and photo adapters in the microscopic range, the adapter according to the invention the advantage of short and handy dimensions with a so associated stability. Essential features of the invention have already been mentioned in the previous one and meanwhile granted main application P 43 00 070.3-31. Beyond that the following aspects arise:

  • 1) zusätzlich zur Anwendung im Videobereich ergibt sich die Anwendung im photographischen Bereich. Es ist von Vorteil, wenn ein Mikroskopiker mit dem erfindungsgemäßen Mikrocam-Adapter nicht nur Videoaufnahmen, sondern auch Photographien machen kann, wodurch sich die Anschaffung eines separaten Photoadapters erübrigt;1) in addition to the application in the video field, there is also the application in the photographic field. It is advantageous if a microscope operator not only with the microcam adapter according to the invention Video recordings, but can also take photographs, which makes the purchase of a separate photo adapter is not necessary;
  • 2) das Hilfsobjektiv besteht aus mehreren Linsen zur Verbesserung der Abbildungsqualität;2) the auxiliary lens consists of several lenses to improve the image quality;
  • 3) je nach zu adaptierenden Geräten liegt die Brechkraft des Linsensystem bei - 10 Dioptrien, jedoch können durchaus auch Abweichungen von diesem Wert möglich sein, solange das Linsensystem insgesamt eine zerstreuende Wirkung hat.3) depending on the devices to be adapted, the refractive power of the lens system is - 10 diopters, however Deviations from this value may well be possible as long as the lens system overall has a diverting effect.
FigurenbeschreibungFigure description

Die einzige Figur zeigt eine Spiegelreflexkamera, die über den Mikrocam-Adapter mit einem Mikroskop verbindbar ist. Hierzu weist der Anschlußring (3) mikroskopseitig ein an das Außengewinde des Adapters (4) angepaßtes Innengewinde auf. Beim direkten Ansetzen des Spiegelreflexkameragehäuses (1) ergibt sich im allgemeinen ein Herabsetzen des Vergrößerungsmaßstabs im Vergleich zum beobachteten mikroskopischen Bild. Um einen normalen Abbildungsmaßstab zu erreichen, kann daher zwischen Mikrocam-Adapter (4) und Spiegelreflexkameragehäuse (1) ein Zwischenring (2) von einer dem normalen Abbildungsmaßstab angepaßten Länge gegeben werden. Einen normalen Abbildungsmaßstab erreicht man dabei mit einer Länge des Zwischenrings (2) von etwa 7-10 cm. Beim Wechseln der Mikroskopobjektive muß gegebenenfalls nachfokussiert werden. Der Zwischenring (2) muß kameraseitig und zu dem Mikrocam- Adapter (4) hin über geeignete Anschlußmöglichkeit verfügen.The only figure shows a single-lens reflex camera, which can be connected to a microscope via the microcam adapter. For this purpose, the connection ring ( 3 ) on the microscope side has an internal thread adapted to the external thread of the adapter ( 4 ). When the SLR camera housing ( 1 ) is directly attached, the magnification scale is generally reduced in comparison to the observed microscopic image. In order to achieve a normal imaging scale, an intermediate ring ( 2 ) of a length adapted to the normal imaging scale can therefore be provided between the microcam adapter ( 4 ) and the SLR camera housing ( 1 ). A normal image scale is achieved with a length of the intermediate ring ( 2 ) of about 7-10 cm. When changing the microscope objectives, it may be necessary to refocus. The intermediate ring ( 2 ) must have a suitable connection option on the camera side and towards the microcam adapter ( 4 ).
