Describe briefly in systematic order the manner or method of properly using a microscope?

Answer 1

The systematic order of properly using a microscope starts with the handling. You should carry it with both hands with one hand supporting the base. When you put the microscope down, put your specimen on the slide and fasten it. Look through the eye piece and adjust the lens as low as possible but without touching the slide.

Answer 2

When you use a compound microscope, the eyepiece must be away from the stage and behind the arm. If you wanted to observe something then you use a wet mount slide. Put a drop of water, use a cover piece (the small 1*1 square) and then use the stage clips, if you have one, to support the slide then look through the eyepiece to look through it.

1. Make sure all backpacks are out of the aisles before you get a microscope! Always carry the microscope with one hand on the Arm and one hand on the Base. Carry it close to your body.

2. Remove the cover, plug the microscope in, and place the excess cord on the table! If you let the excess cord dangle over the edge, your knee could get caught on it, and the next sound you hear will be a very expensive crash.

3. Always start and end with Low Power! The Green means GO! -- "Go ahead and put the slide on the stage." "Go ahead and use the Coarse focus knob." "Go ahead and remove the slide from the stage." "Go ahead and put the microscope away."

4.Place the slide on the microscope stage, with the specimen directly over the center of the glass circle on the stage (directly over the light). Then you have a 9 out of 10 chance of finding the specimen as soon as you look through the eyepiece!

NOTE: If you wear glasses, take them off; if you see only your eyelashes, move closer. Be sure to close, or cover your other eye!!

NOTE: If you see a dark line that goes part way accross the field of view, try turning the eyepiece. That dark line is a pointer that will be very valuable when you want to point out something to your lab partner, or your teacher!

5.If, and ONLY if, you are on LOW POWER, lower the objective lens to the lowest point, then focus using first the coarse knob, then the fine focus knob. The specimen will be in focus when the LOW POWER objective is close to the lowest point, so start there and focus by slowly raising the lens. If you can't get it at all into focus using the coarse knob, then switch to the fine focus knob.

6. Adjust the Diaphragm as you look through the Eyepiece, and you will see that MORE detail is visible when you allow in LESS light! Too muchlight will give the specimen a washed-out appearance. TRY IT OUT!!

7. Once you have found the specimen on Low Power (100x), unless specifically asked to draw it on low power, center the specimen in your field of view, then, without changing the focus knobs, switch it to High Power. If you don't center the specimen you will lose it when you switch to High Power (Yellow).

8.Once you have it on High Power remember that you only use the fine focus knob! The Yellow means CAUTION! -- "Caution, use only the fine focus knob." "Caution, do not remove the slide when it is on High Power." -- The High Power Objective (430x) is very closeto the slide. Use of the coarse focus knob will scratch the lens, and crack the slide. More expensive sounds . . .

Answer 4

When moving your always carry it with both hands. Turn the revolving nosepiece so that the lowest power objective lens is "clicked" into position. Place the microscope slide on the stage and fasten it with the stage clips. Using the coarse adjustment, lower the objective lens down as far as it will go without touching the slide! Look through the eyepiece and adjust the illuminator and diaphram for the greatest amount of light. Slowly turn the coarse adjustment so that the objective lens go up. Move the microscope slide around so that the image is in the center of the field of view and reajust the diaphram for the clearest image. You should be able to change to the next objective lenses with only slight focusing adjustment. The proper way to use a monocular microscope is to look through the eyepiece with one eye and keep the other eye open. Do not touch the glass part of the lenses with your fingers. When finished, raise the tube, click the low power lens into position and remove the slide.
