Labeled Microscope Parts WorksheetsImage - JPGWord DocumentUnlabeled Microscope Parts WorksheetsImage - JPGWord DocumentFunction of each Microscope Part1. Eyepiece or Ocular LensEyepiece lens magnifies the image of the specimen. This part is also known as ocular. Most school microscopes have an eyepiece with 10X magnification. 2. Eyepiece Tube or Body TubeThe tube hold the eyepiece. 3. NosepieceNosepiece holds the objective lenses and is sometimes called a revolving turret. You choose the objective lens by rotating to the specific lens one you want to use. 4. Objective LensesMost compound microscopes come with three or four objective lenses that revolve on the nosepiece. The most common objective lenses have power of 4X, 10X and 40X. Combined with the magnification of the eyepiece the resulting magnification is 40X, 100X and 400X magnification. Total magnification is calculated by multiplying the power of the eyepiece by the power of the objective lens. (10X Eyepiece X 40X Objective = 400X Total Magnification) Some more advanced microscopes have an additional objective lens with 100X power. This results in 1,000X magnification. So where do you start? Which objective lens do you need for a particular task? See “How to Use a Compound Microscope” below. 5. ArmThe Arm connects the base to the nosepiece and eyepiece. It is the structural part that is also used to carry the microscope. 6. StageThe stage is where the specimen is placed. This place is for observation. 7. Stage ClipsStage clips are the supports that hold the slides in place on the stage. 8. Diaphragm (sometimes called the Iris)The diaphragm controls the amount of light passing through the slide. It is located below the stage and is usually controlled by a round dial. How to set the diaphragm is determined by the magnification, transparency of the specimen and the degree of contrast you wish to have in your image. Also called the condenser diaphragm. 9. IlluminatorMost light microscopes use a low voltage bulb which supplies light through the stage and onto to the specimen. Mirrors are sometimes used instead of a built-in light. If your microscope has a mirror, it provides light reflected from ambient light sources like classroom lights or sunlight if outdoors. 10. Coarse focusCoarse focus moves the stage to provide general focus on the specimen. When bringing a specimen into focus, the course dial is the first one used. 11. Fine focusFine focus moves the stage in smaller increments to provide a clear view of the specimen. When bringing a specimen into focus, the fine focus dial is the second one used. 12. BaseThe base is the main support of the microscope. The bottom, where all the other parts of the microscope stand. Quizlet and Kahoot!

Microscope PartsThe 14 Parts of a MicroscopeSometimes microscope parts are listed as the 14 parts rather than the 12 parts as above. If asked for the 14 parts of a microscope, it is generally because the three objective lenses are listed individually instead of as a group. Here are the details: All 11 Parts Listed Above - 12 minus #4 (Objective Lenses)12. Low Power Objective Lens - generally 4x magnification13. Medium Power Objective Lens - generally 10x magnification14. High Power Objective Lens - generally 40x magnificationOther Light Microscope Parts15. Oil Immersion Objective Lens - generally 100x16. Rack Stop17. Condenser Lens

How to Use a Compound MicroscopeUsing a light or compound microscope may seem overwhelming, but it’s really quite easy. Just follow these easy steps to explore microscopic views: A. Place the slide on the stage and secure with clipsB. Center the specimen over the opening in the stageC. Rotate the objective lenses to choose the low power lens (the shortest one)D. Turn the Microscope Light ONE. Rotate the Course Focus (larger dial) while looking through the eyepiece until the specimen comes into clear viewF. Adjust using the Fine Focus dial (smaller) to get a clearer imageG. Carefully rotate to the medium objective lens while keeping everything else the same.H. Minor adjustments to Coarse Focus and Fine Focus may be necessary to get a clear image..What are the 4 steps in using the microscope?Steps on How to Use a Light Microscope. Step 1: Connect the light microscope to a power source. ... . Step 2: Turn the revolving nosepiece so the lowest objective lens is in position.. Step 3: Mount your specimen onto the stage. ... . Step 4: Use the metal clips to keep your slide in place.. What are the steps by steps procedure in using microscope?Place your sample on the stage (3) and turn on the LED light (2). Look through the eyepieces (4) and move the focus knob (1) until the image comes into focus. Adjust the distance between the eyepieces (4) until you can see the sample clearly with both eyes simultaneously (you should see the sample in 3D).
What are the 5 steps in focusing on a microscope?Plug in the microscope.. Turn the microscope light on.. Place the stage as far away from the objective lenses as possible.. Rotate the revolving nosepiece until the lowest power objective lens clicks into place.. Looking at your stage from the side, place the specimen over the hole in the stage.. What are the steps in proper focusing of specimen using a microscope?Center the specimen by moving slide with low power focus. Bring specimen into focus using fine adjustment knob for fine focus on an object with higher magnification. Remove the specimen from the mechanical stage after adjusting fine focus and clean it; lastly, unplug the microscope to turn it off.
