About Fluorescence Microscopy

Functional principle

Fluorescent substances light up when irradi- ated with short-wave excitation light, and fluo- rescence microscopy takes advantage of this property. Specimens without self-fluorescence are stained with a fluorescent substance. One such dye is green fluorescent protein (GFP), which is used in molecular biology.

The Leica M Series

The Leica M series fluorescence stereomicro- scopes allow entire fluorescent specimens to be studied, unprepared and in three dimen- sions. The fully apochromatic optics system and the enormous zoom range make the Leica M series stereomicroscopes your first choice. The patented TripleBeam® third beam path for fluo- rescence illumination and the patented FLUOIII® filter system generate highest-quality fluores- cence images. The very bright high-pressure mercury burner and specially selected filter sets enable you to distinguish the finest structures and enhance the quantity of information for incident light fluorescence.

The filter system

The FLUOIII® filter system consists of a rapid filter changer for barrier and excitation filters and a filter insert for a filter holder with your choice of filter. A total of four filter sets (which are labeled) can be used in the rapid filter changer. An empty filter cartridge is also avail- able for individual filter combinations. Each filter set includes two barrier filters to the visual beam paths and an excitation filter to the illu- mination beam path.
