9 Lens and Imaging System • Lenses are the central component of an imaging system. • Multiple lens sets are used in a complex microscope to provide high magnification and resolution
Magnification and Resolution Confocal STED Magnification vs Resolution What's the difference (c) (d) 圃 Magnification: the lens capacity to expand an image Resolution: the smallest pixel can be spatially differentiated from its closest neighbors 10
