title: Stage-extension device for transmission light microscopes.
abstract: For routine applications, more and more professional microscope users have removed the slide holders from their transmission light microscopes and frequently look over their histological specimens by moving them manually on the microscope stage. This method allows the operator to scan the specimen quickly under survey magnification and thus helps to save time. However, when using detail magnification, moving the sample by hand is simply not precise enough. This drawback becomes particularly evident with photo-documentations or video demonstrations. Here I describe an innovative stage-extension device that allows quick movement of the slide by hand as well as precise positioning of the specimen by using the micrometre fine adjustment of the coaxial stage-drive mechanism.
