Description
Bgletiblitungseinrichtung für medizinische Zwecke. Die vorliegende Erfindung betrifft eine Beleuchtungseinrichtung für medizinische Zwecke mit zwei Linsensysieinen, von denen das der Lichtquelle am. nächsten liegende ein Bild der Lichtquelle entwirft. Der Erfindung gemäß ordnet man zwischen den, beiden Linsensystemen eine in der Richtung der optischen Achsen dieser Systeme verschiebbare Blende an, deren öffnung von dem hinter ihr liegenden Linsensystem abgebildet wird. Durch die Verschiebbarkeit der Blende erzielt man den Vorteil, daß man bei ein für allemal festliegendem Bild der Lichtquelle das Leuchtfeld, d. i. das Bild der Blende, in der Tiefenrichtung etwas wandern lassen, also der Entfernung des zu beleuchtenden Objektes von der letzten Linsenfläche anpassen kann. Die Blende mag man bei dem neuen Gerät entweder als offene, z. B. ringförmige. Blende ausbilden. oder man mag sie auch durch eine Glasplatte, sei :es eine Mattglasplatte, ein Farbglas oder eine Strichplatte, verschließen.Training equipment for medical purposes. The present The invention relates to a lighting device for medical purposes with two Lens systems of which the one closest to the light source is an image of the Light source designs. According to the invention, one arranges between the two lens systems a diaphragm that can be moved in the direction of the optical axes of these systems, whose opening is imaged by the lens system behind it. Through the Movability of the diaphragm gives the advantage that you can do it once and for all fixed image of the light source the luminous field, d. i. the image of the aperture, in the depth direction to wander a little, so the distance of the to be illuminated Can adapt the object from the last lens surface. You like the aperture with that new device either as an open, z. B. annular. Form aperture. or you like it also through a glass plate, be it a frosted glass plate, a colored glass or a Reticle, close.
In der Zeichnung ist beispielsweise eine der Erfindung entsprechend ausgebildete Stirnlampe in einem die optische Achse enthaltenden Schnitt dargestellt. Die Lichtquelle wird hier von dem Glühfaden eitler elektrischen Lampe a gebildet. Hinter der Glühlampe ist ein. Kondensorsystem b und ein Projektionssystem c angeordnet. Zwischen beiden befindet sich eine Blende d, die durch eine Mattglasplatte c abgeschlossen ist. Hinter dem Projektionssystem c liegt ein Spiegel f, der das Strahlenbündel um ungefähr 9o° aus seiner ursprünglichen Richtung ablenkt. Die Blende d ist in der Richtung der Achse A-A verschiebbar. Zu diesem Zweck ist die Fassung der Blende mit zwei Stiften g versehen, die in zwei, Schlitzen h des die ganze Vorrichtung umschließenden. Rohres geführt sind. Optisch ist die Anordnung hier so getroffen, daß der Kondensor b und das Projektionssystem c zusammen ein vergrößertes Bild! des Glühfadens der Lampe a erzeugen und daß das System. c in verhältnismäßig großer Entfernung, die gleich derjenigen ist, die das zu beleuchtende Objekt von der Vorrichtung erhalten soll, ein Bibi der Öffnung der Blende d erzeugt.In the drawing, for example, a headlamp designed according to the invention is shown in a section containing the optical axis. The light source is formed here by the filament of an electric lamp a. Behind the light bulb is a. Condenser system b and a projection system c arranged. Between the two there is a screen d, which is closed off by a frosted glass plate c. Behind the projection system c there is a mirror f which deflects the beam by approximately 90 ° from its original direction. The diaphragm d is displaceable in the direction of the axis AA. For this purpose, the mount of the diaphragm is provided with two pins g which enclose the entire device in two slots h of the. Rohres are performed. The optical arrangement here is such that the condenser b and the projection system c together form an enlarged image ! of the filament of lamp a and that the system. c at a relatively great distance, which is equal to that which the object to be illuminated is to receive from the device, a Bibi of the opening of the diaphragm d is generated.
