Description of this part for the microscope.

molded parts of Carl Zeiss Jena carry their own numbers. This microscope element bears the number 2580 (full designation: Si10 CZ 2580).

This is a service element (replacement part) for the trino head (head with photo output), suitable for Carl Zeiss Jena CF-250 microscopes. Please note that this is a microscope element for a microscope part (the trinocular head) and not a part for a specific microscope model.

Carl Zeiss Jena CF-250 microscopes have a modular design, and the microscope part to which the eyepieces are mounted (commonly referred to as the "head", "binocular" or "binocular tube") is a separate element from the angled tube (sometimes the German term "Winkeltubus" is used). If the angled tube has a photographic output, it is referred to as a "Fototubus". It is precisely for this microscope part that the upper main part of the housing is offered and described here.

Note - although the Carl Zeiss Jena Jenapol and Jenatech microscopes also belong to the CF-250 series, they have a differently constructed photographic output and this housing DOES NOT FIT them.

The exact dimensions of the described and offered microscope element can be seen in the gallery photos. Additionally, in the last photo an arrow indicates which element is being referred to and where it is located in the head, in order to clearly identify this part.

Many different names are commonly used for the trino head. It is worth listing them here - each of them refers to the same microscope part.

assembly of two lenses
- knob for moving and shifting the lenses
- mechanism for moving and shifting the lenses

Metal, cast or injection-molded parts manufactured by Carl Zeiss Jena have their own identification numbers. In this mechanism the lens is mounted on a cast part marked with number 2582 (full marking: Si10 CZ 2582).

This is a service element (repair part) of the trinocular head (photo tube), suitable for Carl Zeiss Jena microscopes of the CF-250 series. Please note that this is an element (component) of a microscope part (German: "Fototubus") and not a part dedicated to a specific microscope model.

Carl Zeiss Jena microscopes of the CF-250 series have a modular design and the microscope part to which the eyepieces are mounted (commonly referred to as "head", "binocular" or "twin tube") is a separate element from the angle tube (sometimes the German term "Winkeltubus" is used). If the angle tube has a photographic output, it is referred to as a "photo tube". The Bertrand lens offered and described here is intended specifically for this microscope part.

Hinweis - Carl Zeiss Jena microscopes Jenapol and Jenatech, although they also belong to the CF-250 series, have a differently designed photographic output and this mechanism DOES NOT FIT these models.

Hinweis - Carl Zeiss Jena also produced a simplified version of the photo tube which does not contain a Bertrand lens inside. In the image gallery there is also a page from the manufacturer's catalog so that it is visible whether these versions differ externally in appearance. This Bertrand lens shown and offered here CANNOT be installed in such a simplified version of the photo tube.

The photos visible in the gallery show the exact dimensions of the element described and offered here. Additionally, in the last photo an arrow indicates which element is concerned and where it is located in the head, in order to clearly identify this part.

In common usage many names are used for the photo tube. It is worth listing them here - each of them refers to the same microscope part.

Description of this part for the microscope.

250 series microscopes.
Note that this element is a component of a microscope element (the angled tube) and not a part dedicated to a specific microscope model.

This element fits, among others, the following Carl Zeiss Jena microscopes from the CF-250 series:
- Jenamed
- Jenaval
- Jenalumar
- Jenavert
- Jenatech
- Jenapol

Important: the element DOES NOT INCLUDE the screw used to secure the microscope head.

Inside this element there is a protective glass (without its own magnification, so called "zero lens") with a violet anti-reflection coating.
Although this holder for the binocular microscope head and the holder located at the photographic port look the same, have the same dimensions and are mechanically compatible - they are NOT (!) identical.
- the binocular microscope head mount contains a protective glass with a violet anti-reflection coating
- the mount located at the photographic port contains a protective glass with a green anti-reflection coating.

The photos visible in the gallery show the exact dimensions of the element described and offered here. Additionally, in the last photo an arrow indicates which element is being referred to and where it is located in the microscope head, in order to clearly identify this part.

objective nosepiece. It consists of slots (empty openings) into which filter sliders are inserted. This is the component that the Microscopy-UK portal (https://www.microscopy-uk.org.uk/mag/imgmar09/JenamedFinal.pdf) referred to as "in-tube filter holders".

This filter holder is compatible with the following Carl Zeiss Jena microscopes:
- Jenamed Variant
- Jenamed Cytology
- Jenamed Hematology
- Jenamed Histology
- Jenamed-2
- Jenamed Fluorescence

Metal, cast, and injection-moulded parts manufactured by Carl Zeiss Jena have their own identification numbers. This part bears the number: 2709/2 (full designation: Si10 CZ 2709/2).

Mechanically, this "block with empty slots" is attached to the casting numbered Si10 CZ 2708, which is the objective nosepiece block.

In the last photo of the gallery, I use an arrow to show exactly which component is being described.

Description of this part for the microscope.

hand when adjusting the interpupillary distance. It is a rounded metal cover that protects the eyepiece prism located underneath.

The last photo in the gallery shows a complete microscope head. An arrow indicates exactly which component is being described and where it is located inside the head, making it easy to identify.

Carl Zeiss Jena wide field microscope heads (those designed for 30 mm eyepieces) have two such components (two prism covers). They protect the prisms of the right and left eyepieces. Both covers are identical and interchangeable, so there is no constructional difference between the right-hand and left-hand cover.

This is a component for a microscope head, not for a specific microscope model.

This component fits microscope heads designed for 30 mm eyepieces used, among others, in the following microscopes:
- Carl Zeiss Jena Jenamed
- Carl Zeiss Jena Jenalab
- Carl Zeiss Jena Jenaval
- Carl Zeiss Jena Jenatech
- Carl Zeiss Jena Jenalumar
- Carl Zeiss Jena Jenavert

Some Carl Zeiss Jena Jenalab and Jenamed microscopes (for example the Jenamed Fluorescence) were factory-equipped with binocular heads accepting 23.2 mm eyepieces. In that case this end cap is **not** compatible with that binocular head. By "that" I specifically mean the binocular head, as this is a component of the head rather than of the microscope itself.

Interestingly, 30 mm wide-field binocular heads are also occasionally fitted to older microscopes from the Mikroval series (for example Ergaval and Amplival). When combined with GF-Planachromat or GF-Planapochromat objectives (the latter also used on the Docuval), this provides arguably the best optical combination available for Carl Zeiss Jena microscopes with a 160 mm tube length.

The Carl Zeiss Jena wide-field binocular head for 30 mm eyepieces is mechanically the same device as the Baader Mark V binocular viewer used with astronomical telescopes. They are based on the same binocular head; the Baader Mark V differs only in having a modified mounting interface, astronomical eyepiece adapters and, in some versions, different external markings. Consequently, the component offered here is also compatible with the Baader Mark V binocular viewer.

Metal cast or injection-moulded components manufactured by Carl Zeiss Jena have their own part numbers. This component is marked with the number 2630 (full designation: Si10 2630 / Si10 CZ 2630). In addition, the number "1" or "2" appears next to the part number to indicate whether it is the cover for the right-hand or left-hand prism. This is the only difference, because mechanically the right-hand and left-hand covers are identical.
