Type of Microscope
Most useful for viewing:
Limitations of this microscope are:
The microscope works by:
Describe the detail that can be seen under this microscope. (You may find it helpful to draw one of the specimens viewed under the microscope.)
Dissecting Microscope
Organisms or objects at relatively low magnifications.
You can only view oranisms that can be seen with the naked eye.
It magnifys up to 40 times the size of the specimens serface by passing throught the glass lenses.
You can see all of the deatails close up on objects that can already been with the naked eye such as the leaf, and feather.You can see the textures of the objects better and see smaller details that would be hard to see without a microscope.
Compound Light Microscope
Small objects that are not visible to the naked eye or finer detail than what can be seen with the naked eye.
It can only magnify up to 40 times until it cannot resolve detai.
Thelight source is below the stage and the light shines up through the specimen and then through the lenses.
You can see things that you can't see with the naked eye. For example when you do 40x zoom on the leaf it kind of looks like a brick wall, you can see different textures and colors that you don'y see just by looking at the object. Transition Electron Microscope
Internal strustures of cells that cannot be viewed under light microscopes
The specimen must be sliced very thin in order for the electrons to go through the.
They pass a beam of electrons through a thin specimen
All of the pictures are black and white and don't show as much detail as the other microscopes.
Scanning Electron Microscope
Studying the details of Specimen's surface.
They cannot be used to view living specimen because the methods used to prepare them for viewing kill cells.
The electron beam scans the specimen's surface which is coated with a thin layer of gold metal.
The pictures are really close up and are in black
