Flashcards about microscopes and protists

Resolution

A term that is important for understanding microscopes; it refers to the ability to distinguish between two objects.

0.2 microns or more

If a microscope had a resolution of 0.2 microns, objects must be this far apart to be seen as two distinct objects.

Light Microscopes

Microscopes that use light to see an image.

Brightfield Light Microscope

A type of light microscope that produces a darker image on a light background.

Darkfield Light Microscope

A type of light microscope that has a light stop, so you see light images on a dark background.

Electron Microscopes

Microscopes that use electron beams to visualize images.

Transmission Electron Microscope

The type of electron microscope most ideal for visualizing structures within a specimen.

Scanning Electron Microscope

The type of electron microscope most ideal for visualizing the 3D surface.

Condenser Lens

The part of the microscope that focuses light on the specimen.

Diaphragm

The part of the microscope that adjusts the level of light.

Objective Lens and Eyepiece Lens

Lenses that work together to get the total magnification in a compound microscope.

4 times

The magnification of the scanning objective lens.

10 times

The magnification of the low power objective lens.

40 times

The magnification of the high power objective lens.

10 times

The magnification of the eyepiece lens.

Coarse Focus Knob

The knob which moves the stage more dramatically to help with focusing

Fine Focus Knob

The knob which moves the stage in smaller increments to help with focusing

Wet Mount

What do you call the action of putting a drop or two of a water sample onto a slide with a coverslip on top?

Lens Paper

The type of paper you must use to clean microscope lenses.
