# Description and specifications:
Replacement element for the HBO 250W fluorescence illuminator for Carl Zeiss Jena Jenalumar microscopes.

This is a spherical rear reflector mounted inside the fluorescence illuminator behind the high-pressure mercury burner. In Carl Zeiss Jena Jenalumar microscopes, the large HBO 250W fluorescence illuminator is attached to the Spiegelhaus for light beam splitting.

The function of this element is to collect and reflect toward the KG filter the light that "shines and escapes to the rear".

This mirror, located directly next to the light source, is susceptible to damage, among other things due to exposure to high temperatures. Additionally, when the high-pressure mercury burner explodes (which occasionally happens), the mirror is very often damaged by the explosion.

The photo gallery shows the exact dimensions of this element. The last photo shows the HBO 250W illuminator for a Carl Zeiss Jena Jenalumar microscope, allowing the compatibility to be confirmed with certainty.
