NEW TECHNIQUES AND APPLICATIONS FOR EPI-ILLUMINATION LIGHT-MICROSCOPY

This modification to the technique of epi-illumination light microscop y makes use of a new system of lenses that replaces expensive and not readily available dipping cone objectives. The newer objectives offer at least comparable resolution and depth of field, along with simple p reparation procedures. An epi-illumination system is a good intermedia te between the stereo microscope and a scanning electron microscope, o ffering magnification at high power that can aid in evaluation of pote ntial scanning electron microscope specimens, as well as the time- and material-saving feature of being able to eliminate unsuitable scannin g electron microscope specimens.
