microscopy Flashcards
It is the ratio of the size of an object seen under the microscope to that of its actual size.
Magnification
it is the ability of the microscope to differentiate 2 close points as separate.
resolving power
it is the distance between the objective and the objective slide
working distance
working distance __________ with increasing ______________
decreases, magnification
it is the ratio of the diameter of the lens to its focal length
numerical aperture
when one objective lens is in focus, then the other objectives will also be in (approximate) focus.
parfocal
it was use for spectacles and magnifying glasses during the 13th century

Invented a way to provide uniform microscope illumination that allowed specimens to be photograpped
August Kohler
he was able to devise a way to allow different magnification
Ernst Leitz
