8. The parts of the microscope are the base-the bottom of the microscope; the arm-crook of the microscope where the base, lenses and stage are connected; the eyepiece-the lens that you look through with a magnification of 10x; the revolving nosepiece-the part where the three objective lenses are; low-power objective-lens with the lowest power of maginifcation at 4x (40x total); high-power objective-lens with the highest power of magnification at 40x (400x total); middle/other-power objective-lens with magnification between the high and low-power objective; stage clips-clips on the stage which hold a slide in place; stage-flat platform on which the slide/specimen is place under the lens; stage opening-hole in the middle of the stage which allows light to hit the slide/specimen from underneath; iris lever/iris diaphragm/disk diaphragm-a lever/disk which controls the amount of light which comes through the stage opening; mirror/lamp-a mirror or lamp beneath the stage which provides lighting for a good view of the slide/specimen. There are light microscopes, where the energy used is light, specimens are thin but can be alive, and its maximum magnification is 100x and the resolution is .0002mm; transmission electron microscopes (TEM), where electrons travel through dead/inorganic specimens to show highly detailed images with maximum magnification at 100,000x; Scanning electron microscopes (SEM), where electrons bounce on the surface of a dead/inorganic specimen in 3D with maximum magnification at 20,000x, Stereodissection scope- a microscope through which you can see the object itself, without slides.
9. Power of a microscope is the power of magnification, or how much a lens can magnify an object. Resolution is the clarity of the specimen, and field is the amount of a specimen you can see at once in the lens. A compound microscope is a microscope which has a mirror/light which illuminates the specimen, objective lens(es) which magnify the object, and an eyepiece (ocular lens) which further magnifies the object. |
