My Microscopes: Leitz Diavert

Fitting a Higher Numerical Aperture Condenser


The Diavert is an inverted microscope which I obtained via eBay to replace a DIY instrument that needed replacement.

Inverted microscopes are generally intended to be used with low resolution long working distance objectives. Leitz do provide an add-on condenser enabling higher resolution objectives to be used, but as I could not locate (or afford!) one of these, I decided to improvise by fitting my own condenser based upon Zeiss components I had in the scrap box. This would then allow me to use any suitable Zeiss condenser.

This view also shows that it is possible to fit a Zeiss trinocular head. This was a temporary measure until I purchased a proper Leitz Diavert trinocular head.


Configuring for Photomicrography

Amazingly, the fibre optic I use with my flash setup was a snug fit in the Diavert lamp housing (see below), so no modifications were necessary other than acquiring a Leitz trinocular head. The final setup with all modifications and additions is to be seen at the top of this page.
