What is stage micrometer?
a tiny ruler that you know the measurements of, and you use it to calibrate the ocular lens of a microscope
Why the calibration of ocular micrometer is used for each objective lens?
It is necessary to superimpose the two scales and determine how many of the graduations coincide with one graduation on the scale of the stage micrometer.
What is the resolution of the 10x objective lens?
It differs from microscope to microscope, so each needs to be calibrated. Even two similar-looking microscopes can have different fields of view. If the ocular lens is 10x then you are seeing things at 100x. One method is to slip a ruler underneath and measure the field of view directly. Some can see 1.76 millimeters in diameter at 10x, which means the image you receive is 176 millimeters (17.6 cm).
How can you use pi to measure the height of an elephant?
One method would be to measure the elephant's shadow and the shadow of a known object with a known height, then use the ratio of the two shadows to determine the elephant's height. Pi comes into play when calculating the angle of the sun's rays hitting the objects to account for the height difference.
What is the spelling of occular?
If you're referring to the word that relates to the eye, the correct spelling is ocular.
Can a calibrated ocular micrometer measure the diameter of the field?
Yes, a calibrated ocular micrometer can be used to measure the diameter or length of a field or object. Essentially, that is all that it is used for.
Why is it necessary to calibrate to ocular micrometer with each objective?
The ocular micrometer is inside the ocular lens, it will not change size when the objectives are changed. Therefore, each objective lens must be calibrated separately. Ocular micrometers have no units on them - they are like a ruler with marks but no numbers. In order to use one to measure something under a microscope, you must assign numbers to the marks. This is done by looking through your OCULAR micrometer at a STAGE micrometer mounted on a slide. The stage micrometer is just a ruler with fixed known distances, so you can use it to tell how far apart marks are on the ocular micrometer. This has to be done because the marks on the ocular micrometer are different distances apart depending on the magnification used on the microscope. It must be calibrated for each objective.
What is ocular micrometer?
An ocular micrometer is a calibration tool used in microscopy to measure the size of objects in the field of view. It consists of a ruler etched onto a glass slide that fits into the eyepiece of a microscope. By comparing the size of objects to the known dimensions on the ocular micrometer, scientists can accurately measure the size of microscopic specimens.

How can you differentiate stage micrometer and ocular micrometer?
Stage micrometer is a glass slide with a scale of known divisions used to calibrate the eyepiece micrometer. Ocular micrometer is a specialized eyepiece with a built-in scale used to measure the size of objects viewed under a microscope. They both help determine the magnification and size of objects but are used at different stages in the setup process.
If thirteen ocular divisions line up with two division of the stage micrometer what is the diameter of a cell that spans sixteen ocular divisions?
Two divisions of the stage micrometer is equal to 20 micrometers. 20 micrometers/13 = 1.54micrometers You multiply this by 16 to find the diameter of the cell. 1.54 x 16 = 24.62 micrometers
What does 1 ocular micrometer division equal on a 10x objective?
1 ocular micrometer scale is equal to 1micrometer when it is seen from 10X objective it will be magnify by 100 times so, 1 ocular micrometer division become 0.1mm ( 1um * 100 = 0.1mm)
What is stage micrometer?
a tiny ruler that you know the measurements of, and you use it to calibrate the ocular lens of a microscope
What is the difference between stage micrometer and ocular micrometer?
Ocular micrometers are see-through disks with a ruler in them that go in the eypiece of a microscope to measure what you are seeing. Stage micrometers are put on the stage/view platform of the microscope, so instead of putting them in the eyepiece you are putting them right next to the object you are looking at in the microscope.
How do the graduations differ between ocular and stage micrometers?
Ocular micrometers are placed in the eyepiece of a microscope and have markings that are viewed alongside the specimen to measure its size. Stage micrometers are placed on the stage of a microscope and have known, predefined distances between markings used as a reference for calibrating the ocular micrometer. The graduations on an ocular micrometer may appear larger or smaller than those on a stage micrometer due to differences in magnification between the two.
Why is the calibration factor for the ocular micrometer specific for each ocular objective combination?
it is because the objectives have different values of magnification.....
Why the calibration of ocular micrometer is used for each objective lens?
It is necessary to superimpose the two scales and determine how many of the graduations coincide with one graduation on the scale of the stage micrometer.
