Handling a Microscope, The digital microscope you are using in science this year costs 900 so. it is very important that you handle it properly Here are five important. rules about handling the microscope , 1 Always place the microscope at least 6 inches 15 24 cm back from. the edge of a table or counter , 2 Never plug the cord into a socket where someone could walk by and. knock it from the table by accidentally walking into the cord Also keep. all cords that are attached to the microscope and the computer away. from water and the end of the table , 3 Always be careful of the objective lenses Follow the instructions in. the FOCUSING THE MICROSCOPE section about how to magnify. properly so that the objective lenses do not get scratched or broken . 4 IF YOU NEED TO carry the microscope use two hands One hand. holds the base The other hand holds the arm ,End of Class How to Clean Up the Microscope.
1 Always place the low power objective lens over the stage in position. for viewing , 2 Use the coarse adjustment knob to lower the stage all the way. 3 Turn off the on off power switch , 4 Carefully unplug the power cord from the microscope and the outlet . Gently wrap the cord and place it in the designated location . 5 Place the cover over the microscope , Parts of the Microscope. Left View Right View, The bottom of the microscope the part it sits on is called the BASE . In the middle of the base pointing upward is a lamp This lamp is called. the LIGHT SOURCE This function of the light source is to project. light through the stage opening so that you can see your slide On the. right side of the microscope is the on off switch LABEL the BASE . ON OFF SWITCH and LIGHT SOURCE on your microscope homework . At the very top of the microscope is the,part you look into It is a lens called the.
EYEPIECE The lens in the eyepiece is,curved glass that makes images appear. bigger by bending the light The,EYEPIECE alone will magnify the specimen. 10X its actual size It does this because,it has one or two curved surfaces The. eyepiece is attached to the top end of a hollow tube called the BARREL. or the TUBE Label the EYEPIECE and the TUBE BARREL . When you look into the eyepiece you will notice a. black arrow pointing to the middle of the view, area You can turn the eyepiece around the. barrel tube point the arrow at various parts of, the enlarged image It s helpful for pointing out.
details to your lab partner s , Lower down on the microscope there is a square flat black slab of metal. with an opening in the middle of it The opening is just above the light. source This is where you put the microscope slide you are going to look. at It is called the STAGE ,Just underneath the stage is a round black. and silver cylinder with a horizontal lever which,you slide horizontally with your finger The. dial adjusts the amount of light that gets, through the hole in the middle of the stage It Diaphragm. is called the DIAPHRAGM , On the bottom left side of the base.
is a dial that also allows you to adjust, the brightness of the light This is. called the BASE DIMMER CONTROL , Use this after you have adjusted the. light using the DIAPHRAGM Label the BASE DIMMER CONTROL . STAGE and DIAPHRAGM on your microscope homework , TOP VIEW BOTTOM VIEW. Stage Adjustment, On top of the stage is a silver clamp of metal screwed into the stage . It is called the STAGE CLAMP The stage clamp holds the microscope. slide in place , Below the stage is a set of knobs called the STAGE ADJUSTMENT.
KNOBS The top larger stage adjustment knob moves the stage. vertically towards you and away from you The bottom smaller stage. adjustment knob moves the stage horizontally left right Label the. STAGE CLAMP and the STAGE ADJUSTMENT KNOBS , Bottom View Top View. Hanging just above the stage, are three pointed tubes called. OBJECTIVE LENSES These, are attached to a round, movable dial called the NOSEPIECE You can use the different objective. lenses by turning the nosepiece Keep your fingers off the lenses Label. the OBJECTIVE LENSES and NOSEPIECE ,The longest objective lens on a. microscope is called the high power,objective lens The high powered lens.
has the number 40X written on it ,This number tells you the. magnification power This 40X lens is,used with the 10X lens in the. eyepiece Together they magnify the,specimen 40 x 10 or 400 times its actual size . The large long bent bar that holds the, eyepiece and the objective lens over the. stage is called the neck or ARM Label it, The knobs between the base and the stage.
are used to focus on the microscope slide , The large knob is called the COARSE. ADJUSTMENT It moves the stage up and, down and provides most of the focus of your. image COARSE ADJUSTMENT is ALWAYS, USED FIRST when starting to focus an. image on low power objective COARSE, ADJUSTMENT is NEVER used on high . power because the stage can move too close to the lens and cause major. damage If you do not follow these directions you damage your. microscope and it will have to be professionally repaired Be careful . The smaller knob is the FINE ADJUSTMENT It is used to bring the. slide into sharp focus Label the COARSE ADJUSTMENT and FINE. ADJUSTMENT on your homework ,Focusing the Microscope.
The coarse adjustment and fine adjustment knobs are very important. parts to handle on the microscope Follow these tips in order to get a. clear image and avoid any damage to the lenses , 1 Always use the coarse adjustment first to get an object in focus on. low power The coarse adjustment will move the stage up and down While. you adjust the knob carefully observe until you see your slide in focus . 2 Sometimes air bubbles or dust will appear when you are focusing and. you will be tricked into thinking that your adjustment is focused on your. slide TO tell if you have been fooled move the stage back and forth. and see if the image moves as well If not try again . 3 Once the coarse adjustment knob has brought your slide into focus . use the fine adjustment knob to sharpen the image . 4 ONLY use the fine adjustment knob on high power 400x The coarse. adjustment knob could cause the stage to bump the lens That could. cause permanent damage to the slide and the microscope lens .
