You can use that to estimate the size of objects that you are observing.
By knowing the diameter of the FOV at a given magnification, you determine the size of the cell or object that you are observing.
Field diameter of lens B equals field diameter of lens A times total magnification of lens A divided by total magnification of lens B
The higher the magnification the lower the depth of field.
The diameter of a field is decreased by 1.5 millimeters when changed from low power to high power magnification.
Adjusting a microscope's magnification settings can alter an object's field of view from a macro to micro areas. Higher magnification make the field of smaller and better defined, where lower settings increases the visible area.
The visibility of the specimen decreases as the power of magnification increases on a microscope. The specimen area will shrink as the magnification is increased.
Magnification is inversely proportional to the diameter of the field of view.
The field of vision shrinks as the magnification gets higher so as the magnification increases the less of the diameter of the microscopic field you can see.
Field diameter of lens B equals field diameter of lens A times total magnification of lens A divided by total magnification of lens B
The higher the magnification the lower the depth of field.
The diameter of a field is decreased by 1.5 millimeters when changed from low power to high power magnification.
When a microscope is parcentered, the specimens will appear centered in the field of view at every magnification. So if a field of a slide is centered at the lowest power, even though the field diameter shrinks at each higher magnification, the desired part of the specimen will remain in the center of the viewing field.
0.75 mm way to get this answer........... (diameter of field A X total magnification of field A) / total magnification of field B so start by finding the diameter of field A= which is the 1.5 next figure out what the total magnification of field A is= 150 (you get this answer by multiplying the ocular # which is 10x by the objective # which is 15x. (10 x 15= 150) next figure out what the total magnification of field B is =300 (you get this answer by multiplying the ocular # which is 10x by the other higher objective # which is 30x. (10 x 30 = 300) then you can use the formula and plug in all the answers you got to get the answer (1.5mm x 150)/300=.75mm
it will increase the magnification of the image of specimen
As the magnification increases, the depth of field decreases.
Increasing the magnification on a light microscope will decreased the diameter of the field of view. You are essentially looking closer and closer at the objects. For example: Using your hand (thumb to fingertips), create a circle as if holding a telescope. Hold your hand-telescope up to one eye and look through it at your screen. Now, move closer to the computer screen... The size of the field you are able to see gets smaller...that's what happens with a microscope lens. As you increase the magnification, the lens gets closer to the specimen.
As you increase the magnification, the field of view decreases.
As you increase the magnification, the field of view decreases.
