Your magnification factor is SID divided by OID. [MF = SID/OID]
So for example:
If your SID was 40 and your SOD was 32
Your magnification factor = 40/32 = 1.25 -- This means the image will appear 25% larger than the actual object. (It's the size of 1 plus 25 percent more of the original.)
Example 2 if you're trying to figure out original object size:
Your object size equals your image size divided by the magnification factor (MF). [object size = image size/ MF]
If you have an object on an image that measure 70 inches when your SID was 100 and your OID was 65, how big was the original object?
MF=100/65= 1.54 (rounded)
Object size = 65/1.54 = 42.21
The object imaged was 42.21 inches before magnification.

mA
What is the magnification factor for a 50MM lens?
A 50mm lens has a diopter of 20.
What is a barlow lens on a telescope?
A barlow lens increases the magnification of the eyepiece usually by a factor of two.
What is parafocal?
parafocal lenses are zoom lenses that preserve the focal plane for every magnification factor.
What happens when the x-ray tube is to close to the chest for an x-ray?
WHILE TAKING A PA VIEW OF CHEST DISTANCE BETWEEN XRAY TUBE AND FILM IS ABOUT 6 FT SO AS TO DECREASE THE MAGNIFICATION AND INCREASE THE SHARPNESS OF IMAGE WHEREAS AN AP VIEW WHICH IS TAKEN AT LESSER DISTANCE THERE IS INCREASED MAGNIFICATION AND DECREASED SHARPNESS. THEREFORE WHEN the X-ray tube is to close to the chest for an X-ray IT CAUSES 1 INCREASED MAGNIFICATION 2 DECREASED SHARPNESS
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.....
Is total magnification an eyepiece magnification plus an objective magnification?
The total magnification is the object magnification for example 4x,10x etc. times eyepiece magnification usually 10x and you get the total magnification. The objective lens magnification is the lens right above the slide usually 4x,10x etc.
What is the antonym for xray?
There is no antonym. An xray is a wavelength. There is no opposite.
How do you calculate total magnification of a surgical microscope with 12.5x eye pieces 175mm objective lens and a 5 step mag changer with ranges 0.4 0.6 1.0 1.6 2.4 x?
if it is 175mm objective,simply multiply u r magnification factor(.4,.....2.4)*eye piece magnifiaction(12.5).......for 2.4,the magnification will be around 30(12.5*2.4).the actula formula is Fbinocular*Meye*zoom factor/Fobj
What is the magnification of the eyepiece on a microscope?
To determine the magnification of the eyepiece on a microscope take the total magnification for the microscope and divide it by the total magnification of the objective lens. The answer is what the magnification is for the eyepiece.
Compare the total magnification of lpo hpo and oio?
LPO has a 10x magnification. HPO has a 40x magnification. OIO has a 100x magnification. LPO has the least magnification, and OIO has the largest.
