It allows you to see a close up of only a small area of the specimen being viewed
An important thing to remember as you turn the high power objective into place , it is RETRACTABLE, when you hit a slide, the end of the lens will push in (spring loaded) thereby protecting the lend and the lens.

microscope consists of two lens called eye lens and objective lens. objective lens is lens kept behind object and eye lens is keep on the top of microscope .i.e. on the place through which we look. firstly the object is placed behind the objective of microscope which is turned into virtual, erect and magnified image. later this image is thought to be the object for the eye lens and this objects forms real, inverted and magnified image.
The three basic structural components of a compound microscope are the head, base and arm. then the main parts are objective lens near object, eye piece near eye and the stage to place object. it has coarse and fine adjustments to focus the object
That depends on which microscope you want to use. For a compound microscope, use the following steps:Place a slide with a coverslip on the microscope's stage.Turn on the light at the microscope's base, or turn the glass disc until you get light to the microscope.Choose the objective lens that you want to use to view your object.Use the coarse adjustment to focus in LOW and MEDIUM power.If you go to HIGH power, use the fine adjustment to focus.If you hold a microscope, hold the arm with one hand and hold the base with your other hand.
On the specimen stage.
Use the fine adjustment on ur microscope its the small knob
It should be stored with the low-power objective in place.
Scanning objective
the nosepeice. it may have other names but this is what i know it as.
Because the objective touches the lens.
Simply, multiply the magnification of the ocular lens times the magnification of the objective lens you have in place.
10 X 10 = 100 magnification. Ocular lens = 10 Objective lens = 10

If only half your viewing field is lit, twist objective lenses until they click into place.
The objective lens with the lowest magnification, usually 4x. Be sure to clean all the lens with lens paper before putting the microscope away.
Some important things to remember in handling a microscope are: When you pick up the microscope and walk with it, grab the arm with one hand and place your other hand on the bottom of the base. Never touch the lenses with your fingers. Your body produces an oil that smudges the glass. This oil can even etch the glass if left on too long. Use only LENS PAPER to clean the glass. When you are finished with your "scope" assignment, rotate the nosepiece so that it's on the low power objective, roll the nosepiece so that it's all the way down to the stage, then replace the dust cover. Clean all slides, materials, and work area when you're done. Please, be careful with the slides and cover slips. They are made of glass and if broken, you will get cut and you will bleed.
You place one hand under the base of the microscope to distribute the weight and not cause damage to the neck of the microscope where important pieces are. It also helps so you don't drop it, two hands are better than one.
