Microscopes

it has light

limited magnification

This is the coarse adjustment knob. This should be used before the fine adjustment knob (the smaller knob) - which is for fine focusing.

compound microscope

oeee

Step 1: Put the specimens in the glass

Step 2: Put it on the stage

Step 3: Look at the eyepiece

Step 4:You can manipulate the microsope!!!!

When you want to look at things you couldn't with a light microscope.

blue light has a shorter wavelength = better resolution

a scanning tunneling microscope measures electrons that leak, or 'tunnel', fromthe surface of specimen

The Dissecting Light Microscope range of magnification is 20x to 80x.

The Compound Light Microscope ranges from 40x to 1000x

-40x Scanning

-100x Low Power

-400x High Power

-1000x Oil Immersion

Hold in upright position with one hand on its arm and the other supporting its base. Avoid swinging it or jarring it when you set it down.

Grasp the arm with one hand while placing your other hand under the base (bottom of the microscope). ALWAYS use two hands.

they are made of glass because it is transparent and nonpermeable so no liquids can pass through it it is hard aswell so it will not break easily

Do not touch lenses. ALWAYS start with the least magnification, and work upwards. Clean slides and microscope when finished with it. Cover microscope with dust cover when not in use. Never swing the microscope.

There are many. Simple microscope, compound microscope, light microscope, scanning electron microscope, Transmission Electron Microscope, Dissection microscope, etc,but all together there are about 20 different types of microscopes.

The smallest thing visible under a light microscope is around 200 nanometers, but this can vary depending on the quality of the microscope and the technique used. To view objects smaller than 200 nanometers, electron microscopes are typically used.

Three uses for microscopes are forensics, reasearch, and analysis.

The arm or the frame of the compound microscope supports the body tube.

five types of microscopes are:

A compound light microscope,the stereo microscope,the electron microscope,a simple microscope(similar to a magnifying glass,and a compound microscope.

The advantages of a monocular microscope is that it is easier to use than a stereo microscope, a disadvantage of the monocular microscope is that it only has a singular eyepiece, therefore, it is harder to see the image. The advantages of a stereo microscope is having two eyepieces, it is easier to focus the eye, and therefore, you can see a more three-dimensional image. A disadvantage for the stereo microscope is that it is a lot more expensive than the monocular microscope.

use for supporting the eyepiece and its objectives.

true

It is used for looking at parts at a very high magnification. It uses a a beam of electrons to create an image of the item being scanned and can magnify it up to 500,000 times.

Two types of electron microscopes are the scanning electron microscope, or SEM, and transmission electron microscope, or TEM.

The inventor of the microscope was Anton Van Leouwenhoek.

He is often called the "father of microscopy".

It was invented in 1608.

It was developed in the Netherlands.

It can only be used for opaque objects.
