Description

Carl Zeiss Jena Jenalumar fluorescence microscope HBO 250W heat absorbing KG-filter glass

KG filter in a metal housing for absorbing heat from the fluorescent lamp of the large HBO 250W illuminator for a Carl Zeiss Jena Jenalumar microscope.

This filter is mounted in the sheet-metal housing of the large HBO 250W fluorescence illuminator. This illuminator is part of a large mirror light beam splitter used in Carl Zeiss Jena Jenalumar microscopes. The KG filter is designed to absorb heat (infrared radiation) emitted by the high-pressure HBO mercury lamp.

Please note that there is also a version of the Carl Zeiss Jena Jenalumar microscopes with a small 50W HBO illuminator. This KG filter glass was removed from a large 250W illuminator.

On the used market, in microscopy forums and in microscopy groups, several names are used for this filter, all referring to the same type of filter:

  • KG filter / KG glass
  • heat filter
  • heat absorbing filter
  • heat absorption filter
  • heat-absorbing glass
  • heat absorption glass
  • absorption filter
  • IR filter
  • infrared blocking filter
  • infrared cut filter
  • KG3 heat absorption filter


This microscope element is highly susceptible to damage. When this happens, the filter needs to be replaced, for example with the filter presented here. Here are examples of damage that can occur during use of the fluorescence illuminator and reasons why replacement of the filter may be necessary:

  • the KG filter may crack or become cloudy due to overheating
  • the filter may also chip or break as a result of mechanical damage, for example during transport
  • the filter may sometimes be damaged during improper maintenance


High-performance heat filters such as this KG filter used with a 250W lamp are very often used by people building their own DIY projects. The housing with screw mounting makes this particularly convenient.

The last photo in the gallery shows the housing of the HBO 250W illuminator (lampenhaus), with an arrow indicating which element is being described and where it is located inside the illuminator. This makes it possible to identify the element unambiguously.
