This is description of this part:
Holder for mounting the objective nosepiece to the microscope arm of a Carl Zeiss Jena Jenalumar microscope.
This component is located between the rotating objective nosepiece and the microscope arm. In the Carl Zeiss Jena Jenalumar microscope, a fluorescence filter cube slides into position above the objective revolver. Inside this holder there is a longitudinal dovetail guide along which the fluorescence filter cubes slide. It also contains a spring steel detent that provides a distinct "click" to indicate the filter position as the fluorescence filter cube is moved along the dovetail guide.
The objective revolver is attached to this holder with screws, and the complete assembly consisting of the holder and objective turret is then screwed to the microscope arm.
The complete objective nosepiece module for Carl Zeiss Jena Jenalumar or Jenaval microscopes consists of:
- the objective revolver (also called the objective nosepiece, nosepiece disc or objective turret)
- the intermediate mounting bracket (nosepiece holder).
In both microscope models, the Carl Zeiss Jena Jenalumar and the Carl Zeiss Jena Jenaval, the first component—the objective revolver—is identical and interchangeable between the two models. Only the intermediate mounting bracket differs, as it attaches the revolver to the microscope arm. In other words, the nosepiece holder used in the Carl Zeiss Jena Jenalumar microscope is different from the one used in the Carl Zeiss Jena Jenaval microscope, but both holders have exactly the same objective revolvers attached to them.
This listing includes only the intermediate holder for the Carl Zeiss Jena Jenalumar model, without the objective nosepiece.
Interestingly, this component is made of aluminium, whereas the corresponding component performing the same function in the Carl Zeiss Jena Jenaval microscope is manufactured from a ZnAl alloy. Cast or injection-moulded ZnAl components made by Carl Zeiss Jena carry identification numbers that allow them to be identified. In the Jenaval microscope this number is 2643 (full marking: Si10 CZ 2643). The objective nosepiece holder used in the Jenalumar does not carry such a number.
Another useful piece of information is that the sliding fluorescence filter cube from the Carl Zeiss Jena Jenamed Fluorescence microscope fits the dovetail guide incorporated into this nosepiece holder.
The gallery includes photographs of the complete assembly consisting of the objective nosepiece and its holder for the Jenalumar microscope, making it clear how these two components are connected.
This database also contains, under item number 99678, the separate objective revolver without the holder.
What is this part needed for?
- this microscope part is suitable as a replacement if the corresponding component in your microscope has been damaged (for example, if the spring detent has come loose)
- if you have a Carl Zeiss Jena Jenalumar microscope without an objective nosepiece and would like to install an objective revolver from a Jenaval microscope
- if you are building your own DIY project using a fluorescence filter cube from a Jenalumar or Jenamed Fluorescence microscope and need this dovetail guide for that purpose
