Introduction to a Microscope.  From ancient times, man has wanted to see things far smaller than could be perceived with the naked eye.

Lab Skills There are certain skills that are needed to perform lab activities. Certain instruments and chemicals must also be used. A simple microscope.

Microscope Vocabulary Terms Total Magnification Field of View Focal Plane Magnify Power Inverted Wet Mount

Total Magnification Multiply the eyepiece magnification by the objective lens magnification. Eyepiece = 10X Low Power = 4X Total Mag. = 10X * 4X = 40X High Power = 10X & 40X Therefore; 100X & 400X

Field of View d d = 4mm 4X

Field of View 10X d d = 1.6mm Inverse Ratio: 10X is 2.5 times greater than 4X, therefore the Field of view is 2.5 times smaller than 4mm. 10X

Field of View d d = ??mm 40X

Field of View d d = .4mm When multiplying/dividing by 10’s, just move the decimal. Multiply moves to Right. Divide moves to Left. 40X

Focal Plane The lens is designed to focus at one distance, from the end of the lens. If the object is not at this distance – it is out of focus. The focused distance is known as the Focal Plane. Items that are above or below the Focal Plane are out of focus.

Magnify Latin Verb To have the power of causing objects to appear larger than they are.

Power Latin Noun Magnification

Inverted Latin – meaning to turn Verb To reverse, to turn upside down, or inside out
