collimating lens and a mirror that reflects light vertically upward.

When attached to the Amplival model, this accessory can convert it into a microscope with EPI illumination.

The last photo shows an excerpt from the user manual describing this accessory.

Description of this part for the microscope.

a CZJ Ergaval / Amplival microscope with a classic illuminator (6V 15W filament bulb) and simply replacing the bulb holder with the one offered here will create a halogen-illuminated microscope. No.
- the original holder of the "regular" bulb contains a lens that collimates the light beam
- the halogen bulb holder does not contain that lens
- Ergaval / Amplival microscopes designed for halogen illumination have an additional lens threaded into the base

Halogen illumination is (according to many experts) the best microscope illumination because it delivers strong light with a full spectrum, whereas LED often provides only a portion of the color spectrum.

Other used names:
- illuminator
- halogen lamp
- bulb holder
- lamp housing

an incandescent lamp illuminator. This lampholder is not required if you have a microscope with the original halogen illuminator - in that case, the collimator lens is a separate element mounted next to the field diaphragm.

Other used names:
- lamp holder
- lamp tube
- lamp support
- sometimes the German-language term "Lampenhaus" is used

Notice - this is NOT a complete illuminator assembly. Please carefully examine the photos in the gallery; as an additional element (which is not included here), a separate silver component extending beyond the outline of the microscope base is screwed in to help support the illuminator with bulb. Here I offer and describe the part that is located inside the microscope base.

Jenalumar 50

Please note the following:
- both microscopes listed here use this illuminator for EPI fluorescence, i.e. reflected light. This is not transmitted-light fluorescence.
- this illuminator requires a Carl Zeiss Jena SH 50 power supply for operation
- the Carl Zeiss Jena Jenalumar microscope was produced in two variants - this illuminator fits the Jenalumar version with two small, separate illumination modules
- information can be found on the Internet claiming that this illuminator is suitable for Carl Zeiss Jena Jenavert microscopes. This is NOT correct.
- an HBO lamp is not the same as an XBO lamp.
- Jenamed microscopes other than the "Fluorescence" version have a differently mounted head and this illuminator CANNOT be installed on them.

Important - operating used, overheated HBO lamps, lamps with unknown operating time or from an uncertain source may result in explosion, damage to the illuminator, contamination of the room and a risk to the user's life and health. For this reason, this illuminator DOES NOT INCLUDE a light source (i.e. it does not include the HBO mercury burner).

transmitted light is inserted. Inside there is a lens that collimates the light beam. In the lower part of this element there are three filter holders and a shutter that allows complete cutoff of this light source.

The illumination block in the Carl Zeiss Jena Fluoval-2 fluorescence microscope is modular, and each of its elements can be easily detached and attached. This microscope element is mounted to the whole module using screws and the key https://www.microscopeparts.eu/part/00588.

illuminator)
Light source: 6V 25W halogen bulb, standard Narva HLWS5-A

This is a complete illuminator consisting of the following components:
- lamp housing with lenses for collimating the light beam
- light source with halogen bulb
- mounting holder for the Citoval-2 / Technival-2 microscope
In the user manual (https://www.mikroskop-online.de/Mikroskop%20BDA/30-725-1%20%20TECHNIVAL%202%20%20CITOVAL%202.pdf) these components are marked as items 7 and 8 on page 4.

Mechanically, this illuminator is mounted on an arm (illuminator holder), which can be clearly seen in the video attached to this description. This holder is attached to a special clamp located on the main objective.
The main objective of the Carl Zeiss Jena Citoval-2 / Technival-2 microscopes has two such clamps, allowing two holders and therefore two illuminators to be mounted. This allows the observed object to be illuminated from both sides. This is exactly why many users look for an additional illuminator.

This illuminator requires a transformer. It uses a 6V low-voltage halogen bulb and therefore cannot be connected directly to a mains power outlet.

The Carl Zeiss Jena Technival and Citoval microscopes (older version without the number "2") are grey, while the Technival-2 and Citoval-2 models are white. This illuminator is white and is therefore intended for the newer Carl Zeiss Jena Citoval-2 and Technival-2 stereo microscopes.

models:
1. Carl Zeiss Jena Jenaval
2. Carl Zeiss Jena Jenalumar
3. Carl Zeiss Jena Jenapol
4. Carl Zeiss Jena Jenavert

1. In Carl Zeiss Jena Jenaval microscopes, this lamp house is used as the transmitted-light illuminator.

2a. In Carl Zeiss Jena Jenalumar 50 microscopes (equipped with the small HBO 50 fluorescent lamp house, identical to the one used in Carl Zeiss Jena Jenamed Fluorescence microscopes), this lamp house serves as the transmitted-light source.

2b. Carl Zeiss Jena Jenalumar 250 microscopes are equipped with a large integrated lamp house. The unit offered here is therefore not compatible with this model.

3. In Carl Zeiss Jena Jenapol microscopes, this halogen lamp house is used both for transmitted light (mounted underneath) and for reflected light (mounted on the top). However, some Jenapol versions are equipped only for transmitted-light operation or only for reflected-light operation.

4. Carl Zeiss Jena Jenavert microscopes are normally equipped with a different lamp housing for reflected light. However, when the original unit is missing, users often modify a lamp house like the one offered here for DIY projects. In addition, if a Jenavert is equipped with a transmitted-light optical path, this lamp house is used as its transmitted-light source.

The lamp house is attached to the microscope using two long screws. Unusually—and this often makes them difficult to find—the screws are removed FROM THE FRONT of the microscope. Their heads are accessible through openings in the white sheet-metal side covers of the microscope body. These covers with the screw openings are shown in this database under item number 99692.

This lamp house contains a filter wheel with four positions for 32 mm diameter round filters. It is fitted with the same filter configuration originally supplied by Carl Zeiss Jena for the Jenaval model:
- one position is empty
- Carl Zeiss Jena C312 blue filter
- Carl Zeiss Jena D282 grey filter
- Carl Zeiss Jena V231 green filter

The filter wheel is an optional part of this lamp house. The example offered here is fitted with it, but it can be removed and the illuminator will still function perfectly as a light source.

Cast or injection-moulded ZnAl components manufactured by Carl Zeiss Jena carry identification numbers. The housing of this lamp house bears the number 2670 (full marking: 2670 Si10 CZ).

In the last photograph, an arrow indicates where this component is located in the microscope, making it easy to identify.

Description of this part for the microscope.

here is not a standalone lamp housing (such as part number 99693 in this database). It is an internal component of the large, integrated illuminator used in Carl Zeiss Jena Jenalumar 250 microscopes.

Carl Zeiss Jena Jenalumar microscopes are available in two main versions:
1. with two small illuminators – with a separate 6 V 25 W halogen illuminator in a small housing (for transmitted light) and a separate HBO 50 W fluorescence illuminator in a small housing (for reflected light)
2. with a large, integrated module consisting of a mirror light splitter, an integrated transmitted-light module with a 6 V 25 W halogen lamp, and a large lamp housing for HBO 250 W fluorescence illumination

The component offered here is part of the second version of the Jenalumar microscope.

Basic parameters of this illuminator module:
Supported lamp: Narva HLWS 6 V 25 W halogen lamp
6 V power connection: this illuminator is connected to the distributor rail (see part number 99679 in this database)
Cooling: passive, in two ways. The Narva HLWS lamp has integrated cooling in the form of “wings”, while the entire illuminator is covered with a cover incorporating a finned heat sink (this is a separate component and is not part of the illuminator offered here)

The photo gallery shows the exact dimensions of this component. The last photo shows the complete HBO 250 W illuminator for the Carl Zeiss Jena Jenalumar microscope, with an arrow indicating this halogen illuminator module. This makes it possible to identify exactly where this component is located within the complete large microscope illuminator.
