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
