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 * 4 = 40X),
the entire field of view is about
5mm or 5,000 micrometers across.
п‚· If an object takes up the entire field of view, it
is
п‚· 5mm or 5,000 micrometers across
п‚· If an object takes up 1/2 the field of view, it is
п‚· 2.5mm or 2,500 micrometers across
п‚· If an object takes up 1/4 the field of view, it is
п‚· 1.25mm or 1,250 micrometers across
Under medium power ~
10x (actually 10 * 10 = 100X),
the entire field of view is about
2 mm or 2,000 micrometers across.
п‚· If an object takes up the entire field of view, it
is
п‚· 2mm or 2,000 micrometers across
п‚· If an object takes up 1/2 the field of view, it is
п‚· 1mm or 1,000 micrometers across
п‚· If an object takes up 1/4 the field of view, it is
п‚· 0. 5mm or 500 micrometers across
Under high power ~
40x (actually 10 * 40 = 400X),
the entire field of view is about
0.45 mm or 450 micrometers across.
п‚· If an object takes up the entire field of view, it
is
п‚· 0.45mm or 450 micrometers across
п‚· If an object takes up 1/2 the field of view, it is
п‚· 0.225mm or 225 micrometers across
п‚· If an object takes up 1/4 the field of view, it is
п‚· 0. 1125 mm or 112.5 micrometers across
Under highest power ~
100x (actually 10 * 100 = 1000X),
the entire field of view is about
0.180 mm or 180 micrometers across.
п‚· If an object takes up the entire field of view, it
is
п‚· 0.180 mm or 180 micrometers across
п‚· If an object takes up 1/2 the field of view, it is
п‚· 0.09 mm or 90 micrometers across
п‚· If an object takes up 1/4 the field of view, it is
п‚· 0. 045 mm or 45 micrometers across
