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.

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.
