What is the relationship between magnification and the diameter of the field of view?

Magnification is inversely proportional to the diameter of the field of view.


What is the relationship between the diameter of the microscope field and its magnification?

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.


How do you calculate field diameter?

Field diameter of lens B equals field diameter of lens A times total magnification of lens A divided by total magnification of lens B


What happend to the depth of field if magnification increases?

The higher the magnification the lower the depth of field.


What happens to the diameter of the field of the view when you change for low to high power?

The diameter of a field is decreased by 1.5 millimeters when changed from low power to high power magnification.


What does it mean for a microscope to be parcentered?

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.


When using a 10X ocular and a 15X objective and the field size is 1.5 mm the approximate field size with a 30X objective is what mm?

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


What will happen to the field of view as you change objectives form 4x to 10x to 40x?

it will increase the magnification of the image of specimen


What happens to the depth of field as the magnification increases?

As the magnification increases, the depth of field decreases.


How does increased magnification affect the field vision?

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.


What is the relationship between the size of the field of view and the magnification?

As you increase the magnification, the field of view decreases.
