Brightfield light microscopy will be used to view microorganisms You will be using a compound microscope. There are 2 oculars on these microscopes therefore they are binocular microscopes. Total magnification = magnification of the ocular lens (10x) multiplied by the objective lens (4x, 10x, 40x, 100x) Resolving power – the distance between two points at which the points can be seen as two separate, distinct entities. Maximum resolution of these compound light microscopes = 0.2μm. If two cells are closer than 0.2μm, they will appear as one cell. Immersion oil reduces the amount of light scattered and lost between the specimen and the objective thereby increasing the resolution up to 0.2μm.
