Description
Stand der TechnikState of the art
Die Forschung in der modernen Zellbiologie möchte im zunehmenden Maße auf optisch sehr stabile Geräte zurückgreifen können. Insbesondere in der konfokalen Fluoreszenz-Mikroskopie muss der Anregungsstrahlengang sehr genau zum Detektionsstrahlengang ausgerichtet sein, andernfalls können die ultra-geringen Lichtmengen aus dem konfokalem Fokusvolumen von z. B. 10^–15 cm^3 nicht detektiert werden, d. h. das Detektionslicht würde verlorengehen. Die Mikroskop-Hersteller setzen bisher im Allgemeinen auf die motorisierte Kalibrierung (Überlagerung) der beiden Strahlengänge (Beleuchtung und Detektion) individuell für jeden dichroitischen Farbteiler, wobei die Positionen der Farbteiler gespeichert werden (
Lösungsolution
Dieser Nachteil der kann erfindungsgemäß dadurch behoben werden, dass ein dichroitischer Strahlvereiniger mit einem Spiegel zur Umlenkung des Probenlichtes in Richtung des Detektionsstrahlengang gekoppelt wird, d. h. eine Spiegelschicht für die Detektionsstrahlung und die dielektrische Schicht für die Strahlvereinigung sich auf einem gemeinsamen optischen Träger (Substrat) befinden. Die Erfindung wird nachstehend anhand der schematischen Darstellungen näher erläutert.
In
Ein Mikroskopstativ S ist mit einer Tubuslinse TL und einem Objektiv Ob zur Fokussierung von Beleuchtungslicht in eine Probenebene PR und zur Übertragung des Probenlichtes in Richtung der Detektion D vorgesehen. Mit dem Stativ S optisch verbunden ist ein Beleuchtungs- und Detektionsmodul BDM. In diesem wird beispielsweise Laserlicht das divergent aus einer Faser F austritt über eine Kollimatorlinse KO kollimiert und über einen Spiegel ST1 und eine Zylinderlinsenanordnung ZL über eine Zwischenbildebene ZB1 und eine weitere Linse L1 an einem dichroitischen Spiegel HFT zur Trennung von Beleuchtungs- und Detektionswellenlängen auf einen Scanspiegel SCM zur scannenden Bewegung der durch ZL erzeugten Beleuchtungsverteilung reflektiert. Das Beleuchtungslicht gelangt über eine Scanoptik SCO, die Tubuslinse TL und das Objektiv Ob in bekannter Weise auf die Probe Pr. Das Probenlicht, insbesondere Fluoreszenzlicht, gelangt rückwärts über den Scanspiegel durch den Hauptfarbteiler HFT (nur über eine Faltspiegelanordnung S2, S3, S4 und eine Pinholeoptik PO sowie einen weiteren Spiegel S5 in kompakter Bauweise fokussiert auf eine Pinholeanordnung PH, die zu der Beleuchtungslinienverteilung in ZB1 konjugierte spaltförmige Einzelpinholes aufweist. Nach der Pinholeanordnung wird das Probenlicht über einen Spiegel S1 und eine Tubuslinsenoptik L2 sowie die Rückseite des Scanspiegels SCM in Richtung der Detektion D gelenkt, bestehend aus einem dichroitischen Strahlteiler und Emissionsfiltern, jeweils vorzugsweise auswechselbar sowie in den Einzelstrahlengängen vor der CCD angeordnet.A microscope stand S is provided with a tube lens TL and a lens Ob for focusing Illumination light in a sample plane PR and for the transmission of the sample light in the direction of the detection D provided. Optically connected to the stand S is a lighting and detection module BDM. In this, for example, laser light which diverges from a fiber F emerges via a collimator lens KO and collimated via a mirror ST1 and a cylindrical lens assembly ZL via an intermediate image plane ZB1 and another lens L1 to a dichroic mirror HFT for separating illumination and detection wavelengths onto a scanning mirror SCM for scanning movement of the illumination distribution generated by ZL. The illumination light passes through a scanning optics SCO, the tube lens TL and the lens Ob on the sample Pr in a known manner. The sample light, in particular fluorescent light, passes back through the scanning mirror through the main color splitter HFT (only via a folding mirror arrangement S2, S3, S4 and a Pinholeoptik PO and another mirror S5 in a compact design focused on a Pinholeanordnung PH, which has to the illumination line distribution in ZB1 conjugated single-pinhole pinholes After Pinholeanordnung the sample light through a mirror S1 and a tube lens optics L2 and the back of the scanning mirror SCM in the direction of Detection D steered, consisting of a dichroic beam splitter and emission filters, each preferably interchangeable and arranged in the individual beam paths in front of the CCD.
Im Rahmen der Erfindung liegt es vorteilhaft auch dass wenn sich im Detektionsstrahlengang eine Kamera, beispielsweise in einem Zwischenbild befindet, auch diese über sie oben beschriebenen Mittel wie das Festkörpergelenk zum Ausgleich des Abdriftens mit einem entsprechenden Spiegel oder einer Linse wie oben beschrieben, verbunden sein kann.Within the scope of the invention, it is also advantageous that if a camera, for example in an intermediate image, is located in the detection beam path, these means such as the solid-state joint described above can also be connected to a corresponding mirror or lens as described above to compensate for drifting off ,
