Question | Answer |
microscope | used to view very small objects |
2 kinds of light microscopes | binocular dissecting microscope compound light microscope |
binocular dissecting microscope | used to study entire objects in 3 dimensions at low magnification |
compound light microscope | used to examine small or thinly sliced objects illumination is from below, light passes through clear sections but not opaque |
eyepiece | occular lens topmost series of lenses |
magnifying power of occular lens | 10 |
body tube | conducts light rays holds nosepiece and eyepiece |
arm | supports upper parts provides carrying handle |
scanning power objectives | magnifying power-40 holds scanning lenses used to view whole slide |
low power objective | magnifying power of 100 holds low power lens to view object in greater detail |
high power objective | magnifying power of 400 holds high power lens to view objects in greater detail |
oil immersion objective | magnifying power of 1000 holds oil immersion lens used in conjunction w oil immersion to view objects w the greatest mangnification |
course adjustment knob | used to bring object into approximate focus used only w low 40 power objective |
fine adj. knob | used to bring object into final focus used w low, high, and oil immersion lens |
diaphragm or diaphragm control lever | controls the amount of illumination |
light source | attached lamp that directs a beam of light up through object, adjust intensity by rheostat button on side |
base | flat surface of microscope that rests on table |
stage | holds and supports microscope slides |
mechanical stage | moveable stage that aids in accurate positioning of slide |
mechanical stage control knobs | two knobs forward/reverse movement,right/left movement |
objective power of: scanning, low power, high power, oil immersion | 4,10,40,100 |
total (x10) magnification and color of: scanning, low power, high power, oil immersion objectives | 40 red course 100 yellow, fine 400 blue, fine 1000 white, fine |
inversion | images appear upside down and reversed |
parfocal | compound microscopes keeps in focus what is in the center |
diamater of field | the circle visible through the lens |
how do you convert from millimeters to micrometers | multiply the millimeter value by 1000 |
3 sources of light | condenser-on the left,under the table rheo stat- red dial on left iris diaphram- knob under table |
meter | primary unit of measure approximately 3 feet |
1 meter= ? centimeters | 100 centimeters |
