Description of this part for the microscope.

housing design.

This is a finned heat sink mounted on the top of the halogen illuminator housing.

Important: The Lux-US halogen illuminator was used exclusively in Reichert Zetopan microscopes.

Reichert Diapan and Reichert MeF-2 microscopes do not use the Lux-US illuminator. However, the illuminators used in these microscopes have an identical mechanical housing and use the same radiator.

Therefore, the radiator offered here is also compatible with these microscopes - it is a repair part for the illuminator housing rather than for a specific microscope model.

Information from the manufacturer's English-language catalogue "Zetopan Research Microscope. Price List, Effective December 1, 1976":
- This component belongs to the microscope illuminator. The catalogue number of the illuminator is: "Lux US" 9 14 41 04 and "Binolux 3 dual lamp housing" 9 60 05 21

In the photo gallery you will find precise dimensions of this microscope part, and the last photograph shows the complete Lux-US illuminator for the Reichert Zetopan microscope so that compatibility can be confirmed with certainty. In that final photograph an arrow indicates exactly which part of the illuminator is being offered.

Older versions of the Reichert Zetopan microscope were equipped with a 6V 30W illuminator, while newer versions used the Lux-US illuminator with a 12V 100W halogen bulb. Currently (as of 2026), most hobby users of this microscope believe that this illuminator should be converted to an LED light source, whereas professional users still prefer a halogen bulb as a light source because it provides a full colour spectrum.

However, in both cases this illuminator housing is essential and must be repaired if damaged. Since it protrudes beyond the outline of the microscope (it is attached to the rear of the microscope base), it is exposed to mechanical damage. The relatively soft cooling fins are susceptible to damage, and in the case of a 100W halogen illuminator efficient passive cooling is very important.

housing.

This is a spherical rear reflector mirror mounted inside the halogen illuminator behind the lamp. The function of this element is to collect and reflect the light that "shines backwards and escapes" and direct it towards the collimating lens.

Important: the Lux-US halogen illuminator was used exclusively in Reichert Zetopan microscopes.

Reichert Diapan and Reichert MeF-2 microscopes do not use the Lux-US illuminator, however the illuminators used in these microscopes have an identical mechanical housing and use the same rear reflector mirror.

Therefore, the mirror presented here is also compatible with these microscopes - it is a repair part for the illuminator rather than for a specific microscope.

Older Reichert Zetopan microscope models were equipped with a 6V 30W illuminator, while newer models used the Lux-US illuminator with a 12V 100W halogen lamp. Currently (as of 2026), most amateur microscope users believe that this illuminator should be converted to an LED light source, while professional users still prefer a halogen bulb as a light source because of its full colour spectrum.
However, in both cases this lampenhaus is essential and must be repaired if damaged. Since it protrudes beyond the outline of the microscope (it is attached to the rear of the microscope base), it is exposed to mechanical damage. The mirror located directly next to the light source is susceptible to damage, among other reasons, due to exposure to high temperatures. In addition, over the decades the mirror surface may oxidise, causing the mirror to lose its optical properties and the entire illuminator to lose brightness.

housing.

This is a lamp socket (plug-in assembly with bulb) that slides into the illuminator housing.

Reichert Diapan and Reichert MeF-2 microscopes do not use the Lux-US illuminator, however the illuminators used in these microscopes have an identical mechanical housing and use the same lamp socket.

However, in both cases this lampenhaus is essential and must be repaired if damaged. Since it protrudes beyond the outline of the microscope (it is attached to the rear of the microscope base), it is exposed to mechanical damage.

The lamp socket is particularly sought after by users who want to convert the illuminator to a different light source, for example LED. For this purpose, the plug-in assembly usually needs to be modified irreversibly - and it is best to do this using a "spare" lamp socket rather than "destroying" the original one.

Note - this lamp socket does not include the plastic end cap. It is not essential for operation - however, I would like to point this out.
