Microscope Magnification

Field of View 10x Magnification

Field of View 20x Magnification

Field of View 30x Magnification

Field of View 40x Magnification

Field of view it is the diameter of the circle of light that you see when looking into a microscope. As the power gets greater, the field of view gets smaller.

Micrometer a unit of length in the metric system one millionth of a meter Used to be called the micron. Symbol = mm

Under low power ~ 4x (actually 10 Under low power ~ 4x (actually 10 * 4 = 40X), the entire field of view is about 5mm or 5,000 micrometers across. If an object takes up the entire field of view, it is 5mm or 5,000 micrometers across If an object takes up 1/2 the field of view, it is 2.5mm or 2,500 micrometers across If an object takes up 1/4 the field of view, it is 1.25mm or 1,250 micrometers across

Under medium power ~ 10x (actually 10 Under medium power ~ 10x (actually 10 * 10 = 100X), the entire field of view is about 2 mm or 2,000 micrometers across. If an object takes up the entire field of view, it is 2mm or 2,000 micrometers across If an object takes up 1/2 the field of view, it is 1mm or 1,000 micrometers across If an object takes up 1/4 the field of view, it is 0. 5mm or 500 micrometers across

Under high power ~ 40x (actually 10 Under high power ~ 40x (actually 10 * 40 = 400X), the entire field of view is about 0.45 mm or 450 micrometers across. If an object takes up the entire field of view, it is 0.45mm or 450 micrometers across If an object takes up 1/2 the field of view, it is 0.225mm or 225 micrometers across If an object takes up 1/4 the field of view, it is 0. 1125 mm or 112.5 micrometers across

Under highest power ~ 100x (actually 10 Under highest power ~ 100x (actually 10 * 100 = 1000X), the entire field of view is about 0.180 mm or 180 micrometers across. If an object takes up the entire field of view, it is 0.180 mm or 180 micrometers across If an object takes up 1/2 the field of view, it is 0.09 mm or 90 micrometers across If an object takes up 1/4 the field of view, it is 0. 045 mm or 45 micrometers across
