The ability of the microscope to show fine structural details with clarity and sharpness is…
resolution
What part of the microscope turns on the light source?
main/power switch
What part of the microscope regulates the amount of light to the microscope?
brightness adjustment knob
What part of the microscope provides white light?
light source/LED bulb
What part of the microscope is known as the area underneath the stage?
substage assembly area
What part of the microscope changes light in a fine tune manner?
iris/aperture diaphragm with lever
What part of the microscope prevents the light from scattering as it travels from the bottom?
condenser lens
What setting on the field setting disk is used for dyed specimens that are nonliving?
bright field (BF) setting/microscopy
What setting on the field setting disk is used for non-colored/dyed specimens that are living?
dark field (DF) setting/microscopy
What part of the microscope rests the slide/specimen on top of it?
stage
What part of the microscope moves the slide back and forth and side to side, functioning in scanning the slide starting at the lowest magnification?
slide adjuster knob
What part of the microscope is NOT used for measuring size of specimen, but are used as coordinations for positioning/pinpointing a landmark on the slide?
scale of specimen position
What part of the microscope is responsible for the primary magnification of the image; contains four different lenses and magnifies at four different levels?
objective lens
What part of the microscope is used to change from one objective to the next objective?
revolving nose piece
What part of the microscope is the closest to the eyes and ALWAYS magnifies the image to 10x?
ocular lens (eyepiece)
What part of the microscope moves the stage up and down and allows for the initial, rough focus?
coarse adjuster/focus knob
What part of the microscope allows only fine movement of the stage and results in a later, fine focus?
fine adjuster/focus knob
What is known as the area you can see when looking through the microscope?
field of vision
There is an inverse relationship between…
(hint: theres 2 answers)
range of field and magnification
depth of field and magnification
What is known as the distance between the objective lens and the specimen?
depth of field
A specimen has ______ planes known as the ________________
several
planes of focus
The __________ gets you to any one of several planes of focus, but the _________ gets you to the center plane of focus = goal! = better resolution.
coarse focus knob
fine focus knob
What type of light contains a short wavelength that penetrates deeper into the specimen, providing better resolution?
blue light
