This application claims priority of International Application No. PCT/EP01/11368 filed Oct. 2, 2001 and German Application No. 100 50 677.1, filed Oct. 6, 2000, the complete disclosures of which are hereby incorporated by reference.
a) Field of the Invention
The invention is directed to a fluorescence turret for inverted microscopes which contains fluorescence cubes. These fluorescence cubes can be brought into operative position selectively in order to carry out different examinations in fluorescence microscopy.
b) Description of the Related Art
As is known, these fluorescence cubes comprise exciter filters in the direction of the light source, dichroic splitter mirrors and blocking filters in the observation direction. Turrets of this kind are known from DE 2316386, for example.
It is the object to improve on the design of fluorescence turrets for inverted microscopes and to overcome disadvantages of the prior art.
In accordance with the invention, a reflector turret for an inverted microscope comprises a cover which is water-tight at least at the top and substantially light-tight outside the microscope beam path.
In the drawings:
The beam path of an inverted microscope is shown schematically in
A protective glass SG is provided in the cover A. This protective glass SG releases the optical beam path downward and protects against liquid at the same time. The protective glass is removable for cleaning, changing or in case of troublesome reflections and, for this purpose, is located in a frame F which snaps into the hood. However, the glass plate of the protective glass SG itself is advantageously fitted into the cover A at an angle not equal to 90° to the optical axis, preferably with a deviation of 3 to 5 degrees from the vertical.
While the foregoing description and drawings represent the present invention, it will be obvious to those skilled in the art that various changes may be made therein without departing from the true spirit and scope of the present invention.
