Abstract
Description
Die Erfindung betrifft eine Beleuchtungseinrichtung in einem Mikroskop mit mehreren Lichtquellen, die an einem Spiegelhaus angeordnet sind und mittels eines Spiegels im Spiegelhaus wahlweise dem Beleuchtungsstrahlengang zuordenbar sind.The invention relates to a lighting device in a microscope with a plurality of light sources, which are arranged on a mirror house and by means of a mirror in the mirror house optionally the illumination beam path can be assigned.
Beleuchtungseinrichtungen dieser Art sind bekannt bei Mikroskopen, die beispielsweise in mehreren Spektralbereichen abbilden und entsprechend mehrere Lichtquellen aufweisen. Die Spektralbereiche können beispielsweise den sichtbaren, den infraroten oder den ultravioletten Spektralbereich oder spektrale Bereiche oder Spektrallinien-Linien darin betreffen. Diese Beleuchtungseinrichtungen enthalten den Spektralbereichen zugeordnete Lichtquellen.Lighting devices of this type are known in microscopes, which image for example in several spectral regions and correspondingly have a plurality of light sources. The spectral regions may, for example, relate to the visible, the infrared or the ultraviolet spectral region or spectral regions or spectral line lines therein. These illumination devices contain light sources assigned to the spectral regions.
Dazu ist es bekannt, im Beleuchtungsstrahlengang zwischen der eigentlichen Lichtquelle und der Beleuchtungsoptik eine sogenanntes 2-faches Spiegelhaus anzuordnen, an dem zwei Lichtquellen angebracht sind. Zur Umschaltung zwischen den beiden Lichtquellen ist meistens ein klappbarer Spiegel angeordnet. Ein manuelles Umschalten zwischen den Lichtquellen ist meist umständlich und kostet unnötige Zeit, da die Schaltmechanismen teilweise schlecht zugänglich sind.For this purpose, it is known to arrange a so-called 2-fold mirror house in the illumination beam path between the actual light source and the illumination optics, to which two light sources are attached. For switching between the two light sources usually a hinged mirror is arranged. A manual switching between the light sources is usually cumbersome and costs unnecessary time, since the switching mechanisms are sometimes difficult to access.
Weiterhin kommt es zu einem hohen Zeitverlust beim Austausch von einer defekter Lampe, da die Umgebung der Lampe und diese selbst sehr heiß ist. Ist der zweite Anschluss bei einem 2-fachen Spiegelhaus frei, schaltet man einfach zur zweiten Lichtquelle um, ist dieser aber mit eine Lichtquelle für ein anderes Verfahren belegt, muss man seine Arbeit unterbrechen, bis das System abgekühlt ist.Furthermore, there is a high loss of time when replacing a defective lamp, since the environment of the lamp and this itself is very hot. If the second port is free for a 2-mirror house, you simply switch to the second light source, but if it is assigned a light source for another procedure, you must stop working until the system cools down.

Es ist daher Aufgabe dieser Erfindung, eine Beleuchtungseinrichtung in einem Mikroskop mit mehreren Lichtquellen anzugeben, welche eine schnelle, motorische Umschaltung zwischen mehreren, speziell bis zu drei Lichtquellen ermöglicht.It is therefore an object of this invention to provide a lighting device in a microscope with multiple light sources, which allows fast, motorized switching between several, especially up to three light sources.
Diese Aufgabe wird bei einer Beleuchtungseinrichtung in einem Mikroskop mit mehreren Lichtquellen, die an einem Spiegelhaus angeordnet sind und mittels eines Spiegels im Spiegelhaus wahlweise dem Beleuchtungsstrahlengang zuordenbar sind, durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst.This object is achieved with a lighting device in a microscope with multiple light sources, which are arranged on a mirror house and by means of a mirror in the mirror house optionally the illumination beam path can be assigned, solved by the characterizing features of
Um hierbei eine Redundanz zu gewährleisten, können bei dieser Erfindung alle drei Anschlüsse bestückt sein, wobei an zwei Anschlüsse die gleichen Lichtquellen kommen. Fällt eine Lichtquelle aus, kann sofort zur andere umgeschaltet werden.In order to ensure redundancy in this case, all three ports can be equipped in this invention, with two ports, the same light sources come. If one light source fails, you can switch to the other immediately.
Dieses Verfahren könnte automatisiert werden, wenn die Funktion der Lichtquellen mittels eines Lichtsensors überprüft würden. Meldet ein Sensor den Ausfall der einen Lichtquelle, könnte automatisch durch eine intelligente Ansteuerung des Motors auf die andere Lichtquelle gleicher Art umgeschaltet werden.This method could be automated if the function of the light sources were checked by means of a light sensor. If a sensor reports the failure of one light source, it could automatically be switched to the other light source of the same type by an intelligent control of the motor.
Durch die Möglichkeit, den Spiegel mit Spiegelhalter aus dem Spiegelhaus herausnehmen zu können, kann dieser auch jederzeit durch einen anderen Spiegel ausgetauscht werden. Wenn dann eine spezielle Untersuchung auch spezielle Spiegelbeschichtungen verlangt, kann ein anderer Spiegel mit geforderter Spezifikation (Wellenlänge, Reflektionsschicht, Farbe, Form, o. ä.) eingesetzt werden.By being able to remove the mirror with mirror holder from the mirror house, this can also be replaced at any time by another mirror. If then a special investigation also requires special mirror coatings, another mirror with required specification (wavelength, reflection layer, color, shape, etc.) can be used.
Auch braucht bei Beschädigung des Spiegels das Spiegelhaus nicht mehr zur Reparatur eingeschickt, sondern nur ein Ersatzspiegel bestellt werden.Also, if the mirror is damaged, the mirror house no longer needs to be sent in for repair, but only a replacement mirror can be ordered.
