Calculating Total Magnification

Magnification of ocular lens

10x

Magnification of Scanning lens

4x

Magnification of Low Power lens

10x

Magnification High Power lens

40x

Magnification of Oil Immersion lens

100x

Total Magnification

Equal to the power of the ocular lens multiplied by the power of the objective lens being used magnifies 45x, total magnification is 450x (10 x 45).

TM of Scanning

40x

TM of Low Power

100x

TM of High Power

400x

TM of Oil Immersion

1,00x

Depth of Field

the amount of (thickness) of a specimen that is in focus

Parfocal

lens design that allows specimens to remain near focused at different magnification powers

Working distance

amount of space between the upper surface of the glass slide and the lowest part of the objective lens.

Field

Eyepiece Lens: The lens at the top of the microscope that you look into. They are usually 10X
