MICROSCOPE

functional microscope

TermDefinition
Light Microscope The lenses bend or refract the light, which makes the object beneath them appear closer.
Light Microscope the models found in most schools, use compound lenses and light to magnify objects.
Scanning Electron Microscope allow scientists to view a universe too small to be seen with a light microscope.
Transmission Electron Microscope also uses electrons, but instead of scanning the surface (as with SEM's) electrons are passed through very thin specimens.
Magnification How much larger an object appears under a scope than it actually is
Oculars engraved with their magnifying powers
Eyepieces (Oculars) the part of the microscope that magnifies the image produced by the microscope's objective so that it can be seen by the human eye.
Resolution The rendering of detail
Light the limiting factor of resolution
Blue Light allows resolution of 0.2 microns
Depth of Field The distance through which you can move the specimen and still have it in focus
Higher Magnification the closer the objective is to the slide and so the depth of field decreases
Depth of Field requires more delicate technique
Microscopy talks a lot about magnification
Resolution most important function of microscope
Things to use to clean the microscope Lens paper or gauze & cleaning solution
