microscopes Flashcards
what is an eyepiece lens
the lens you look down
what is an objective lens
closest to the sample
what is magnification
the number of times greater that an image is than the actual object
what is resolution
the ability of a microscope to show two objects as separate
how do you calculate magnification
magnification = image size / actual size
what source does a light microscope use
light source
what source does a SEM and TEM use
electron source
how many micrometres are in a millimeter
1mm = 1000 micro metres
which microscope has the lowest resolution
light microscopes
what are light microscopes useful for
studying whole cells or tissues
what is the maximum magnification of a light microscope
around x1500
what do confocal microscopes use as a source
laser beams
what image is produced from a confocal microscope
3D
when do you use a confocal microscope
look at objects at different depths in thick specimens
what is good about electron microscopes
high resolution and high magnification
