What is a parfocal - Study guides, Class notes & Summaries

If the total magnification of a microscope can be increased by simply adding more lenses, why are bright-field light microscopes not outfitted to magnify things greater than 1300×? correct answers Because the resolution limit for a light microscope is about 0.2μm, magnifications above this will not produce clear images. Fluorescent microscopy differs from other types of light microscopy in that it requires correct answers the use of an ultraviolet light source. Why is it important to cen...
