Light microscopy CORRECT ANSWER - Uses visible light to examine microscopic-sized objects that cannot be seen by the naked eye. - Allows finer detail than the naked eye. Electron microscopy CORRECT ANSWER - Visualize objects much smaller than those resolved optically. - Use accelerated electrons instead of light photons. - Samples are fixed with chemicals to cross-link molecules to preserve their structure. Fluorescent stains CORRECT ANSWER - Used with light microscopy. - Fluorescence ...

When taking a fundus photo and you see a blue gray halo around the eye, you should move the camera correct answers closer As flurescein dye circulates throughout the eye and sequential pictures are taken,this is known as correct answers Angiograms For the slit lamp photography, in order for an image to be produced in each ocular and in the camera, a is necessary. correct answers Beam Splitter The reticule in the slit lamp and fundus camera is to compensate for the refractive error corre...
