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.

Can the same calibration factor be used to determine the size of a microorganism under all objectives?
With each objective, the calibration must be recalibrated because the calibration only applies to its calabrated objective.
The parts and functions of the parts of a microscope?
Arm = supports top part of microscope Base = the part the microscope stands on Lens turret= a rotating support for the objective lenses objective lens or lenses are those closest to the object being viewed. Their degree of magnification is usually marked on the side of the lens, eg. 100x magnifies the object 100 times. The longer the lens, the greater its magnifying power. Eyepiece (or ocular lens) = This is the lens closest to the eye and its magnifying power is generally marked on the side. To determine the total magnifying power of a compound microscope, multiply the power of the ocular lens with the power of the objective lens. For example, a 10x ocular with a 100x objective would give a total magnification of 1000. A microscope may also have a binocular eyepiece with a lens for each eye. Stage Clip= holds the glass slide which contains a specimen to be viewed. Stage- holds the specimen. Coarse adjustment knob- makes large adjustments to the focus of the lenses. Fine adustment knob- makes small adjustments to the focus of the lenses Below the stage is located either a mirror or an electric light which directs light through the specimen on the stage.
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).
Why aren't the magnificaions of both ocular lenses of a binocular microscope used to calculate total magnification?
Because each eye needs its own magnified image. Put another way: Your brain doesn't add the magnification power of the image seen on the left to the magnification power of the image seen on the right. If only one ocular was magnified, you wouldn't be able to see the magnified image in both eyes---the eye with the unmagnified image would see unmagnified and the eye with the magnified image would see magnified. Am I understanding the question correctly?
Why is screw gauge commonly called as micrometer screw gauge?
A micrometer screw gauge is commonly known as a micrometer. This is a form of calipers used for measuring small dimensions. Screw gauge in extensively used in the engineering field for obtaining precision measurements. The article describes the principle and main parts of a basic micrometer screw gauge.
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 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 the total magnification for each lens setting on a microscope with 15X ocular and 4X 10X 45X and 97X objective lenses?
Multiply the Ocular strength by the Objective strength. In this case: 60x, 150x, 675x, 1455x

10 times eye piece 40 times objective lens?
Each objective lens has a different magnification. Multiply the magnification of the eyepiece by the magnification of the objective lens to produce total magnification. For example, a 10X ocular lens and a 40X objective lens will produce a total magnification of 400X (10 x 40 = 400).
What is the total magnification for each lens setting on a microoscope with 15x oculars and 4x 10x 45x and 97x objectives lens?
With 8X eyepiece and 5X objective lens , Its magnification is 40X while with 8X eyepiece and 4X objective lens , Its magnification is 32X.
What is the distance between each of the graduations on the stage micrometer?
0.01mm
How to get a best calibration management software solution?
A better calibration management system contributes to higher quality maintenance and production. It is the crucial part of remaining compliant with the various ISO standards or manufacturing regulations from FDA. Qualityze calibration management software allows you to track calibration history for each piece of equipment which includes previous calibration dates, results, and any issues that were found. This software also offers automatic tracking of calibration intervals based on regulatory or internal requirements.
Check equipment calibration at the beginning of each spraying season and after every hours of use?
50 to 100
Are nature and objective are synonyms of each other?
no
