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

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 ~ 4 x (actually 10 * 4 = 40 X), the

Under low power ~ 4 x (actually 10 * 4 = 40 X), the entire field of view is about 5 mm or 5, 000 micrometers across. If an object takes up the entire field of view, it is 5 mm or 5, 000 micrometers across If an object takes up 1/2 the field of view, it is 2. 5 mm or 2, 500 micrometers across If an object takes up 1/4 the field of view, it is 1. 25 mm or 1, 250 micrometers across

Under medium power ~ 10 x (actually 10 * 10 = 100 X), the

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

Under high power ~ 40 x (actually 10 * 40 = 400 X), the

Under high power ~ 40 x (actually 10 * 40 = 400 X), 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. 45 mm or 450 micrometers across If an object takes up 1/2 the field of view, it is 0. 225 mm 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 ~ 100 x (actually 10 * 100 = 1000 X), the

Under highest power ~ 100 x (actually 10 * 100 = 1000 X), 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
