Attaching Zeiss 100 W illuminator to epi-illumination port on Zeiss IM microscope

The following photos show the (now working as it has a new bulb) Zeiss 100 W illuminator attached to the epi-illumination port, and light coming through into the base of the objective turret through the epi-illumination port. Unfortunately, this is not sufficient to use epi-illumination yet. I have a flourescence cube holder which fits into the space under the objective turret and directs light up into the objective lens. This currently only has flourescence filters on it, which remove most of the light, seriously dimming the image. Hence I need to modify that cube holder to allow all light to be re-directed without filtering. I think this will involve purchasing a purpose-cut mirror…..but I still need to look into it.
