Study Notes

Microscope Basics

The word 'microscope' originates from the Greek words 'mikros' meaning small and 'skopein' meaning to see, literally meaning "to see small things".
A magnification of '100x' means that the image is enlarged 100 times its original size.

Magnification in a Microscope

The total magnification in a microscope is determined by multiplying the power of the ocular lens (eyepiece) by the power of the objective lens.

Resolution in Microscopy

Resolution in the context of microscopy refers to the minimum distance between two points that can still be distinguished as separate.
The resolving power of the unaided human eye is approximately 200 micrometers (μm).
The formula for determining total magnification in a microscope is: Total Magnification = Ocular Power x Objective Power.

Limitations of Magnification

If there is increased magnification without improved resolution in a microscope, it does not provide more detail, but rather a larger, blurrier image.

Calculating Total Magnification

If the ocular power is 10x and the high power objective is 50x, the highest magnification achievable using this microscope is 10 x 50 = 500x.
