Calculating Total Magnification

Working distance

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

Parfocal

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

Depth of Field

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

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).

Field

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