Please note that exactly the same (!) illuminator is also used on the Zeiss Standard / Photomicroscope series microscopes. Please refer to the description of illuminator No. 99684 in this database. YES – these are exactly the same illuminators. However, that particular unit was removed from a Zeiss Photomicroscope II and therefore has its own separate description. You will also find additional photographs and an extended description there.

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.

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).

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.

light source to be connected. The lamp house is installed on the left side of the microscope, while the built-in mirror prism redirects the light beam into the EPI nosepiece.

Fluorescence light sources are most commonly connected to this mount, but it is completely universal. It contains no filters and can be used with LED, HBO, XBO, halogen or even classic incandescent lamp houses.

If the light source is lightweight (one of the newer models), it can be mounted without any additional supports. If a large, heavy lamp house is used, additional support frames are often employed to carry its weight (these are optional accessories and are not included).

In its current configuration, this mount accepts lamp houses with a 48 mm connection diameter. However, this mounting adapter can be removed, leaving a plain tube that can accept virtually any adapter, allowing almost any manufacturer's light source to be connected.

The last photograph in the gallery shows a Zeiss Photomicroscope III microscope with this lamp house mount installed. An arrow indicates its exact location, making it easy to identify this component.

The video gallery also contains two videos. The first presents this component from different angles and in close-up. The second demonstrates how to remove this EPI lamp house mount using a Zeiss Photomicroscope III microscope (commonly known as the Zeiss Phomi III) as an example.

Description of this part for the microscope.

microscope base. It transfers the light beam from the illuminator, homogenises it (the image of the filament is diffused by means of a diffuser), and then properly collimates it using a collimating lens. The prepared light beam is then directed to the deflecting mirror (this is a separate microscope component).

This is part of the transmitted-light optical path. The diffuser (frosted ground glass) and the collimating lens are housed inside a metal enclosure that serves as a heat sink for the halogen lamp. The complete assembly forms the illuminator housing.

This particular collector with frosted ground glass was removed from a Carl Zeiss Photomicroscope (also known as Zeiss PM / Zeiss Phomi).
It fits the following microscopes (this is not a complete list):
- Zeiss Photomicroscope (Zeiss PM / Phomi)
- Zeiss Photomicroscope II (Zeiss PM2 / Phomi II)
- Zeiss Photomicroscope III RS (Zeiss PM3 RS / Phomi III)
- Zeiss Universal
- Zeiss Ultraphot
- most likely also Zeiss Standard 16 / 18 / WL / WL 89 / GFL microscopes

VERY IMPORTANT: This component is intended for the 6V 15W incandescent illuminator. Zeiss microscopes may be equipped either with a 6V 15W incandescent illuminator (a tubular illuminator inserted into the microscope base) or with an external halogen Lampenhaus mounted to the rear of the microscope base. Microscope versions equipped with a halogen illuminator use a different illuminator holder than the one presented here.

Other names used for this component:
- illuminator holder with frosted filter
- illuminator tube
- illuminator holder with frosted ground glass
- sometimes the foreign-language term "Lampenhaus" is also used, although it is not a precise name for this component

The last photographs in the gallery show the base of a Zeiss Photomicroscope III RS. Arrows indicate exactly which component is being offered and where it is located inside the microscope base, making it possible to identify this component unambiguously.

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.

are equipped with a base illuminator using a 6 V 15 W lamp. This can be replaced with:
a) a large 60-watt illuminator using a 12 V 60 W lamp
b) a halogen illuminator

This listing presents the illuminator described in option a), namely the 60 W incandescent lamp version.

Basic specifications of this illuminator:
Manufacturer: Carl Zeiss (Oberkochen, West Germany)
Model: 60-watt illuminator
Lamp voltage: 12 V
Lamp house mounting method: circular dovetail
Cooling: passive. The entire large lamp house also serves as a heat sink, dissipating the heat generated by the 60-watt lamp
Lamp socket centering screws: yes, the lamp socket is equipped with centering screws
Diffuser: yes, inside the lamp house, in front of the lamp condenser lens (the so-called illumination collector), there is a matte diffuser mounted in a flip-out holder

This particular unit was removed from a Carl Zeiss Photomicroscope II. However, it is compatible with most microscopes of the Zeiss Standard series.

This illuminator fits the following microscopes:
- Zeiss Standard 16 / GFL
- Zeiss Standard WL / WL 89
- Zeiss Universal
- Zeiss Photomicroscope
- Zeiss Photomicroscope II
- Zeiss Photomicroscope III RS
- and also the Zeiss IM 35 / ICM 405 inverted microscope

The following is a quotation from the Zeiss Photomicroscope II instruction manual:

60-watt illuminator

Instead of the 6-v. 15-w base illuminator, the 60-watt illuminator may be firmly connected to the microscope stand. For this purpose, the collector tube with lamp condenser, 46 70 50, must be removed after unscrewing the bottom plate and replaced by the connecting tube, 46 70 41 (Fig. 15). The 60-watt illuminator is mounted in the usual manner with the aid of a dovetail ring, like a body tube, for example.

The variable transformer is identical to the one for the base illuminator and supplies voltages from 0 ... 20 volts. When this equipment is used, the red scale of the voltmeter applies.

Several important points should be mentioned:
- if your microscope is currently equipped with the standard 6 V 15 W illumination system, the illuminator mounting adapter must also be replaced (this is described in the instruction manual quoted above)
- the lamp house of this illuminator is finished in grey. Some Carl Zeiss Standard series microscopes have black, cream or hammered-finish housings. This illuminator is mechanically compatible with those models, although the colour may not be an aesthetically perfect match
- power supplies with a rated output of exactly 60 W are virtually unavailable on the second-hand market. In practice, 12 V 100 W power supplies are used to operate this light source
- please note that exactly the same (!) illuminator is also used on the Zeiss IM 35 / ICM 405 inverted microscopes. Please also refer to the description of illuminator No. 00697 in this database. YES – these are exactly the same illuminators. However, that particular unit was removed from an inverted microscope and therefore has its own separate description. You will also find additional photographs there. In the Zeiss IM 35 instruction manual, the lamp socket is referred to as "Lamp socket 60 P/N 46 80 15", while the lamp house is referred to as "Lamp housing with lamp condenser P/N 46 72 27"
- this illuminator can be used for both transmitted-light and reflected-light (EPI) illumination
- if you would like to manufacture your own DIY illuminator mounting adapter because you do not have the original Zeiss part (P/N 46 70 41), the following information may be useful: the circular dovetail on this illuminator has a diameter of 43 mm, which is the same as on many microscope condensers and mono-, binocular and trinocular microscope heads. This means that, for example, a microscope head mounting adapter can be used as the basis for manufacturing a custom DIY illuminator adapter

Important: The photographs show a lamp installed in the lamp socket. This lamp DOES NOT LIGHT because it is burned out. It is shown only so that you can see which lamp model is used in this illuminator.

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.
