Description of this part for the microscope.

microscope. It will most likely also fit other models from the Jenamed series (e.g. Jenamed Variant, Jenamed Fluorescence, Jenamed-2, Jenamed Hematology). Please note however that the Carl Zeiss Jena Jenamed Histology microscope is factory-equipped with a different type of condenser - the "flip-out" type.

To make sure whether this condenser will fit a specific Carl Zeiss Jena microscope from the Jenamed series, it is best to carefully check all dimensions based on the gallery photos or ask a question on a professional forum, e.g. https://www.mikroskopie-forum.de/

Mechanically, this condenser is mounted from the underside of the microscope stage - first it is screwed into the threaded opening in the stage and then secured with three screws. The upper lens can be unscrewed to obtain a condenser with a lower numerical aperture N.A. This condenser does not have an iris diaphragm installed because in Jenamed microscopes it is a separate element.

Replacing the condenser in a Carl Zeiss Jena Jenamed microscope may be necessary:
- when the upper lens becomes damaged, for example when it turns matte due to exposure to various chemical reagents
- when the upper lens becomes damaged due to rubbing. Surprisingly, this unusual type of damage is very common after several decades of microscope use.

In the last photo I indicate with an arrow exactly which element it is and where it is located in the microscope.

therefore cannot be used in:
- Jenamed Cytology
- Jenamed Variant
- Jenamed Hematology
- Jenamed Fluorescence
- Jenamed-2

Mechanically, this condenser is a "flip-out" design and is mounted in a metal frame together with a lever used to rotate it in order to obtain one of two operating modes: low or high numerical aperture N.A. This lever extends outside the microscope housing so that the user can operate it.

The complete module is mounted underneath the microscope stage by attaching the entire condenser assembly from below with four screws. This condenser does not contain an iris diaphragm because, in Jenamed microscopes, it is a separate component mounted beneath the condenser.

In the Carl Zeiss Jena Jenamed Histology microscope, this condenser is not used together with the wide-field lens that is installed beneath the condenser in other Jenamed models (part Si10 CZ 2711-1). In the Jenamed Histology model, a polarizer is installed in this position instead.

Replacement of the condenser in a Carl Zeiss Jena Jenamed Histology microscope may be necessary:
- when the upper lens becomes damaged, for example by becoming cloudy due to exposure to various chemical reagents
- when the upper lens is damaged by friction. Surprisingly, this unusual type of damage is very common after several decades of microscope use
- when the mechanical lens switching mechanism ("flip-out") becomes damaged

Metal cast or injection-moulded microscope parts manufactured by Carl Zeiss Jena carry their own part numbers. This condenser module bears number 2713 (full marking: Si10 CZ 2713).

In the last photograph, I indicate with an arrow exactly which component is being offered and where it is located within the microscope.

2 Fluorescence

It DOES NOT FIT Carl Zeiss Jena microscopes from the Jenamed series and therefore cannot be used in:
- Jenamed Cytology
- Jenamed Variant
- Jenamed Hematology
- Jenamed Histology

Mechanically, this condenser is mounted on the microscope stage support plate (stage support). The microscope stage is installed onto this support plate together with the condenser. The upper condenser lens can be unscrewed - after removing it, the condenser operates with a lower numerical aperture N.A.

This condenser does not contain an iris diaphragm because, in Jenamed microscopes, it is a separate component mounted beneath the condenser.

Replacement of the condenser in a Carl Zeiss Jena Jenamed-2 microscope may be necessary:
- when the upper lens becomes damaged, for example by becoming cloudy due to exposure to various chemical reagents (common in fluorescence applications)
- when the upper lens is damaged by friction. Surprisingly, this unusual type of damage is very common after several decades of microscope use

Metal cast or injection-moulded microscope parts manufactured by Carl Zeiss Jena carry their own part numbers. The microscope stage support plate on which the condenser is mounted bears number 3030 (full marking: Si10 CZ 3030).
