Carl Zeiss Jena Jenaval microscope - 30 mm eyepiece tubus with diopter adjustment ring - thumbnail [ 99135 ] video	SERMIK_ID number under which this microscope part is placed in the database. 99135	Carl Zeiss Jena Jenaval microscope - 30 mm eyepiece tubus with diopter adjustment ring	The name of this microscope part. Carl Zeiss Jena Jenaval microscope - 30 mm eyepiece tubus with diopter adjustment ring	Description of this part for the microscope. Eyepiece tube with a 30 mm diameter for the eyepiece mount of a Carl Zeiss Jena microscope head. This is a tube with an assembled diopter adjustment ring that ... allows correction of vision in one eye and proper adjustment of image focus. Basic parameters: - Type: tube with diopter correction ring - Diameter of supported eyepieces: 30 mm - Color: white Fits 30 mm heads used, among others, in the following Carl Zeiss Jena 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.

904 - Thumbnail photo showing this microscope part. Carl Zeiss Jena Jenamed / Jenaval microscope lighting brightness adjustment knob - thumbnail [ 99458 ] video	SERMIK_ID number under which this microscope part is placed in the database. 99458	Carl Zeiss Jena Jenamed / Jenaval microscope lighting brightness adjustment knob	The name of this microscope part. Carl Zeiss Jena Jenamed / Jenaval microscope lighting brightness adjustment knob	Description of this part for the microscope. Light intensity adjustment knob for Carl Zeiss Jena CF-250 group microscopes. Compatible with the following Carl Zeiss Jena microscopes: - Jenamed (models ... Variant, Cytology, Hematology, Histology, Jenamed-2, Fluorescence) - Jenapol - Jenavert - Jenaval - Jenatech - Jenalumar Please note - this is only the adjustment knob, that is the knob used by the microscope user to make the illumination brighter or dimmer. It is not a potentiometer and therefore not a part of the electrical circuit. This knob features the characteristic white cap used on Carl Zeiss Jena microscopes, which is often lost during decades of microscope use. Mechanically, this knob is attached to the potentiometer. The fixing screw is covered by a white metal cap. In the last photo I indicate with an arrow exactly which element it is and where it is located in a Carl Zeiss Jena Jenamed microscope. In Jenaval and Jenalumar microscopes it is located on the microscope base. Names, descriptions, terms, and search contexts under which this part is searched.

An eyepiece tube with a 30 mm diameter for installation in a Carl Zeiss Jena microscope head. This is an eyepiece tube without diopter adjustment. ... Carl Zeiss Jena microscope heads with a wide field of view (German: Grossfeld) have one eyepiece tube with diopter adjustment and a second one without it. Here I present the tube without diopter adjustment (straight eyepiece tube). Basic parameters: - Type: straight eyepiece tube - Compatible eyepiece diameter: 30 mm - Colour: white Compatible with 30 mm microscope heads 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.
