Description
BeschreibungDescription
Einrichtung zur Erhöhung der Tiefenschärfe bei Mikroskopen.Device for increasing the depth of field in microscopes.
Mikroskope üblicher Bauart besitzen eine sehr geringe Tiefenschärfe. Diese wird geringer je größer die Vergrößerung der Mikroskope ist. Dies ist bei Beobachtung von dreidimensionalen Objekten (z. B. Tiere) hinderlich.Conventional microscopes have a very shallow depth of field. This becomes smaller the higher the magnification of the microscope. This is a hindrance when observing three-dimensional objects (e.g. animals).
Der im Schutzanspruch 1 angegebenen Erfindung liegt das Problem zugrunde, eine Einrichtung zu schaffen, die eine höhere Tiefenschärfe ermöglicht, als die der gewöhnliche Mikroskopen.The invention specified in claim 1 is based on the problem of creating a device that enables a greater depth of field than that of conventional microscopes.
Dieses Problem wird mit den in Schutzanspruch 1 aufgeführten Merkmal der Verschiebung Schärfenebene, in einer Geschwindigkeit die schneller ist als die Trägheit des menschlichen Auges, erreicht.This problem is solved by the feature of shifting the focal plane as set out in claim 1 at a speed that is faster than the inertia of the human eye.
Mit der Erfindung wird erreicht, daß der Eindruck der Tiefenschärfe bei der Beobachtung erhöht ist, da die Schärfenebene die Bewegung über das Objekt wandert.The invention achieves that the impression of depth of field during observation is increased, since the plane of focus moves over the object.
Bei der Einrichtung gibt es drei Möglichkeit der Ausführung.There are three options for setting it up.
1. Die Bewegung des Beobachtungsobjekt(BO) und des Objektiv (01)
zueinander. Dies läßt sich am einfachsten durch vibrierenden Objektträger
(OT) verwirklichen. Dies hätte dann auch den Vorteil der Nachrüstung für
bestehende Mikroskope.1. The movement of the observation object (BO) and the lens (01)
to each other. This can be done most easily by vibrating the slide
(OT). This would also have the advantage of retrofitting for
existing microscopes.
2. Die Bewegung eines optischen Zwischengliedes (ZG) im Strahlenganges
zwischen Objektiv (01) und Okular (O2). Dies hätte den Vorteil, daß sich das
Beobachtungsobjekt und das Mikroskop sich selbst bewegen.2. The movement of an optical intermediate element (IC) in the beam path
between the objective (01) and the eyepiece (O2). This would have the advantage that the
The object being observed and the microscope itself move.
3. Die Bewegung des Objektiv (O1) und des Okular (O2) zueinander.3. The movement of the objective lens (O1) and the eyepiece (O2) relative to each other.
Die beschrieben Bewegungen müssen mit einer hören Frequenz ausgeführt werden als das Auge durch sein Trägheit wahrnehmen kann (>100Hz). Die Größe der Bewegung wird der verwendeten Vergrößerung, durch Anschläge oder der Ansteuerung, angepaßt. Die Bewegungen können sehr elegant elektromagnetisch oder pizoelektrisch erzeugt werden.The movements described must be carried out at a frequency higher than the eye can perceive due to its inertia (>100Hz). The size of the movement is adapted to the magnification used, by means of stops or control. The movements can be generated very elegantly electromagnetically or pizoelectrically.
