|---|---|---|---|---|---|
| Microscope | an instrument that produces an enlarged image of an object
🗑
|
||||
| Lens | an optical device that refracts (Bends) light to form images
🗑
|
||||
| Simple microscope | a microscope with one lens
🗑
|
||||
| Compound light microscope | named because they use two or more lenses to magnify objects. Highest possible magnification is 1,000X
We use a microscope of 400 x
🗑
|
||||
| Electron Microscope | Do not use lenses to direct light; they use electrons (negatively charged electrical particles) to magnify objects up to 2,000,000X!!! allow scientists to view things too small to be seen with a light microscope.
Used to observe atoms and molecules
🗑
|
||||
| Eyepiece Lens | the lens at the top that you look through.
🗑
|
||||
| Body Tube | Connects the eyepiece to the objective lenses.
🗑
|
||||
| Objective Lenses | Usually you will find 3 objective lenses on a microscope. They almost always consist of 4X, 10X, 40X - magnify objects/specimens
🗑
|
||||
| Nosepiece | This is the part that holds the objective lenses and can be rotated to change power.
🗑
|
||||
| Base | The bottom of the microscope, used for support.
🗑
|
||||
| Arm | Supports the tube and connects it to the base
🗑
|
||||
| Light source | found near the base of the microscope; makes the specimen easier to see.
🗑
|
||||
| Stage | The flat platform where you place your slides.
🗑
|
||||
| Stage clips | found on the stage; hold the slides in place.
🗑
|
||||
| Diaphragm | rotating disk under the stage; different sized holes vary the intensity and size of light that is projected upward into the slide.
🗑
|
||||
| Coarse adjustment knob | large, round knob on the side of the microscope used for focusing the specimen; it moves the stage up and down.
🗑
|
||||
| Fine adjustment knob | small, round knob on the side of the microscope used to fine-tune the focus of your specimen after using the coarse adjustment knob.
🗑
|
||||
| Magnification | is the process of enlarging something only in appearance, not in physical size
🗑
|
||||
| Field of View | The area of the slide that you see when you look through a microscope; it is the circle of light.
🗑
