Abstract

In a microscope objective (1) comprising a housing (2), which is connectable to an objective mount of a microscope and comprises a light inlet opening (6), and further comprising an optical system (8) arranged inside the housing (2), an image-detecting element (19) is provided and light entering through the light inlet opening (6) is directed to the image-detecting element (9) by means of the optical system (8) and is not coupled into a beam path of the microscope, said beam path being located following the microscope objective.

Claims

1. A microscope objective (1) comprising a housing (2), which is connectable to an objective mount of a microscope and comprises a light inlet opening (6), and further comprising an optical system (8) arranged inside the housing (2), characterized in that an image-detecting element (9;

27) is provided and that light entering through the light inlet opening (6) is directed to the image-detecting element (9;

27) by means of the optical system (8) and is not coupled into a beam path of the microscope, said beam path being located following the microscope objective (1).

2. The microscope objective (1) as claimed in claim 1, characterized in that the image-detecting element (9) is arranged inside the housing (2).

3. The microscope objective (1) as claimed in claim 1, characterized in that the housing (2) comprises a light outlet opening (25) and that the image-detecting element (27) is arranged outside the housing (2).

4. The microscope objective (1) as claimed in claim 3, characterized in that the image-detecting element (9) is attached to the outside of the housing (2) in such a manner that it covers the light outlet opening.

5. The microscope objective (1) as claimed in claim 3, characterized in that an optical device (26) is provided between the housing (2) and the image-detecting element (27).

6. The microscope objective (1) as claimed in any one of claims 1 to 5, characterized in that an evaluating device (13) is arranged outside the housing (2), said device being able to receive electrical image signals generated by the image-detecting element (9).

7. The microscope objective (1) as claimed in claim 6, characterized in that the evaluating device (13) is attached to the outside of the housing (2).

8. The microscope objective (1) as claimed in any one of claims 1 to 7, characterized in that the image-detecting element (9) is connected to the housing (2).

9. The microscope objective (1) as claimed in any one of claims 1 to 8, characterized in that a second image-detecting element (27) and a beam splitter (28) are provided, with the light entering through the light inlet opening (6) being split into two partial beam paths so as to illuminate both image-detecting elements (27, 9).

10. The microscope objective (1) as claimed in any one of claims 1 to 9, characterized in that the microscope objective (1) comprises a dark field channel (19) for illuminating a specimen (7) to be photographed.

11. The microscope objective (1) as claimed in any one of claims 1 to 10, characterized in that a light source (15;

16) is provided in the housing (2).

12. The microscope objective (1) as claimed in claim 11, characterized in that light from a light source (15;

16) may be output by at least a part (10) of the optical system (8) through the light inlet opening (6).

13. The microscope objective (1) as claimed in any one of claims 1 to 12, characterized in that the image-detecting element (9) comprises a CCD image sensor.

14. The use of the microscope objective (1) as claimed in any one of the preceding claims in a microscope comprising an objective mount, to which an observing objective is attached, and an optical observing system which is arranged following the objective mount and wherein specimen light received via the observing objective is coupled in if the observing objective is arranged in its working position using the objective mount, the microscope objective (1) being connected to the objective mount and movable into its working position by the latter.
