I don't remember the specifications for the Jenatech.

Note: this is the version with the frosted glass; there are also versions without it.

documentation, this element is referred to in German as -Fototubus 100/100 und Tubusträger-.

This is a photographic tube on which a binocular microscope head is mounted - in this configuration it becomes a complete trinocular system. At the top there is an optical output where a camera or photographic device can be mounted.

Basic technical parameters:
- light beam splitting: 0/100 and 100/0
- head mounting method: dovetail 41.5 mm
- mounting method on the photographic port: dovetail 41.5 mm
- internal lens: additional Bertrand lens e.g. for phase contrast adjustment
- extras: slot for installing a filter wheel

Note - despite certain similarities, this microscope element DOES NOT FIT Carl Zeiss Jena Jenamed microscopes.

allows two filters to be inserted into the EPI optical path, for example a frosted diffuser filter, a blue colour-balancing filter or a green filter used to facilitate metallurgical observations.

The photographs in the gallery show the exact dimensions of this slide.

positions: 6
- Thread: M25
- Mounting method: screw-mounted to the intermediate bracket (nosepiece holder), between the nosepiece and the microscope body

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 revolver attached to them.

This offer includes only the objective turret, without the mounting bracket.

The gallery contains photographs of a Carl Zeiss Jena Jenalumar microscope arm, with the objective nosepiece indicated by an arrow to clearly show its location. It also includes photographs of the complete module consisting of the objective revolver and its holder for the Jenalumar microscope, making it clear how these two components are connected.

This database also contains, under item number 99388, the complete objective nosepiece module with its holder for the Carl Zeiss Jena Jenaval microscope.

knobs (via a pinion mounted on the shaft between the knobs) into the vertical movement of the integrated microscope stage and condenser support. This support is mounted on a dovetail guide, which is an integral part of the focusing block (included with this assembly).

This mechanism is suitable for the following microscope models:
- Carl Zeiss Jena Jenalumar
- Carl Zeiss Jena Jenaval
- Carl Zeiss Jena Jenavert

Description of this part for the microscope.

The complete set presented here consists of three components:
1. a small metal plate marked with the numbers 1 to 8 – these identify the terminal positions
2. an electrical tab terminal strip with eight terminals, housed in a plastic body
3. the rear sheet-metal cover of the microscope arm with the printed 6V illumination wiring diagram

This set was removed from a Carl Zeiss Jena Jenalumar microscope.

Components "1" and "2" (the numbered plate and the electrical tab terminal strip) are universal and fit the following microscope models:
- Carl Zeiss Jena Jenalumar
- Carl Zeiss Jena Jenaval
- Carl Zeiss Jena Jenavert
- Carl Zeiss Jena Jenapol

Component "3" (the rear sheet-metal cover of the microscope arm)
- fits the Carl Zeiss Jena Jenalumar microscope
- does not fit the Carl Zeiss Jena Jenaval microscope
- I do not know whether it fits the Carl Zeiss Jena Jenavert or Jenapol microscopes, as I have not personally tested this.

The 6V supply wires coming from the power supply are connected to the input terminals on the underside of this electrical tab terminal strip. The power supply is built into the microscope base. The lampenhaus fitted with a 6V 25W halogen bulb is connected to the output terminals on the upper side. In the Carl Zeiss Jena Jenaval and Jenalumar microscopes this supplies the transmitted-light illuminator. In the Carl Zeiss Jena Jenavert microscope it supplies the reflected-light illuminator.

In microscope versions equipped with two illuminators, only one of them can be powered from the power supply built into the microscope base, because the built-in power supply has a maximum output power of 25 W. The second illuminator requires an external power supply appropriate for the particular light source (a halogen lamp, a fluorescence light source, or—in the case of LED illuminators—an LED power supply with a dimmer).

This database also contains, under item number 99694, the same component together with the rear sheet-metal cover of the microscope arm from a Carl Zeiss Jena Jenaval microscope. You can compare the two versions to see the difference in the size of the rear sheet-metal cover between the Carl Zeiss Jena Jenaval and Jenalumar models.

If you need only one component from this set—either the rear microscope arm cover or only the electrical tab terminal strip—please contact us by email or through social media.

Description of this part for the microscope.

It is not an illuminator holder in the literal sense. The illuminator is secured with screws to the sides of the microscope's vertical arm. Instead, the central circular opening in this component is designed to receive and accurately position the cylindrical light-output section of the illuminator (lamphouse).

Microscopes designed for reflected-light operation (either exclusively or in addition to transmitted light), such as the Carl Zeiss Jena Jenalumar, Jenavert and Jenapol-U, have a different upper horizontal microscope arm from models intended exclusively for transmitted light, such as the Carl Zeiss Jena Jenaval. The reflected-light arm includes a slot for filter sliders, a slot for an aperture slider and, of course, an angled mirror.

Interestingly, this component is also present in Carl Zeiss Jena Jenaval microscopes, even though the standard version of this model is not equipped with an EPI reflected-light illuminator. Since it is not used there, it is normally covered by the rear sheet-metal cover of the microscope arm. This is exactly why the rear cover of the Carl Zeiss Jena Jenalumar microscope is shorter than that of the Jenaval model—it does not have to cover this component (see item no. 99679 in this database).

This component fits the following microscope models:
- Carl Zeiss Jena Jenalumar
- Carl Zeiss Jena Jenaval
- Carl Zeiss Jena Jenavert
- Carl Zeiss Jena Jenapol

- in the Carl Zeiss Jena Jenaval microscope this component is hidden behind the rear sheet-metal cover and is not used
- in the Carl Zeiss Jena Jenalumar 50 this component receives the small 50W HBO fluorescence illuminator
- in the Carl Zeiss Jena Jenalumar 250 with the large integrated lamphouse, this component receives the light-output section of the 250W HBO fluorescence illuminator
- in the Carl Zeiss Jena Jenavert this component receives the 50W/100W halogen illuminator
- Carl Zeiss Jena Jenapol microscopes may be equipped with various EPI reflected-light illuminators

Cast or injection-moulded ZnAl components manufactured by Carl Zeiss Jena carry identification numbers that allow them to be identified. This component bears the number 2650 (full marking: Si10 2650).
