10x Objective Lens Total Magnification

The full magnification depends upon the power of the ocular times the power of the objective lens. Then in a typical lab microscope yous would probable find a 10X ocular and three or four objective lenses: 4X, 10X, 40X (45X in some scopes, and 100X. The total magnification for each of these would be 40X, 100X, 400X (450X), and 1000X. Some older scopes take 47X and 97X as objective lenses so those would be 470X and 970X. If you demand the total magnification for the microscope yous used, you'll have to get it from the microscope itself! To calculate the total magnification, you multiply the power of the ocular lens by the power of the objective lens. For example, if your ocular lens has a power of 10x and your objective lens has a power of 5x, your total magnification will be 50x. Practise that simple job for each of what you lot asked and y'all volition be good to go. Don't forget to include the "ten" in your answers.

1000 = Mo x Me find Mo the object is placed only outside the focal length of objective lens Mo = – di/practice and di = 16 cm , do = 0.8 Mo = – 16 / 0.eight = -twenty find Me the object (the epitome from objective lens) is place only inside the focal length di = -25 cm , do = ii.5 cm Me = – (-25) / 2.five = +10 so

M = -20 (+10) = -200

When you become a good response, please consider giving a best answer. This is the merely reward nosotros get.

Figuring Total Magnification

Magnifying Objects/ Focusing Image:

When viewing a slide through the microscope make certain that the stage is all the way downward and the 4X scanning objective is locked into place. Place the slide that you want to view over the aperture and gently move the phase clips over top of the slide to hold it into place. Beginning with the 4X objective, looking through the eyepiece making certain to continue both eyes open (if you lot have trouble cover one eye with your hand) slowly move the stage upward using the coarse aligning knob until the image becomes articulate. This is the but time in the procedure that you will need to use the coarse adjustment knob. The microscopes that you lot volition be using are parfocal, significant that the image does not need to be radically focused when changing the magnification. To magnify the image to the side by side level rotate the nosepiece to the 10X objective. While looking through the eyepiece focus the prototype into view using only the fine aligning knob, this should only accept a slight turn of the fine adjustment knob to complete this chore. To magnify the epitome to the adjacent level rotate the nosepiece to the 40X objective. While looking through the eyepiece focus the epitome into view using only the fine adjustment knob, this should but take a slight turn of the fine adjustment knob to complete this job.

Total Magnification:

To figure the full magnification of an epitome that y'all are viewing through the microscope is really quite simple. To go the total magnification take the power of the objective (4X, 10X, 40x) and multiply past the power of the eyepiece, normally 10X.
