The Compound Light Microscope What is it? The microscope pictured above is a compound light microscope. The term light refers to the method by which light transmits the image to your eye. Compound deals with the microscope having more than one lens.
Microscope is the combination of two words; "micro" meaning small and "scope" meaning view. Parts and Uses Eyepiece and Body Tube The eyepiece contains the ocular lens which magnifies
objects a given amount that is listed on the eyepiece. The body tube supports the eyepiece and objectives. How much do our microscopes magnify? Nosepiece, Objectives, and Stage Clips The nosepiece holds the 3
objectives. The objective lenses range in magnification from 4X, 10X, and 40X. The stage clips holds the slide in place. Nosepiece Magnification What happens as the power of magnification increases?
Stage, Light, and Diaphragm The stage supports the slide being viewed. The light source projects upward through the diaphragm, the specimen, and the lenses. The diaphragm
regulates the amount of light on the specimen. Arm and Base The arm is used to support the microscope when it is carried. The base supports the
microscope. Coarse Adjustment Knob Moves the stage up and down for focusing. NOT TO BE USED WITH ANY OTHER OBJECTIVE BUT THE 4X
Fine Adjustment Knob Moves the stage slightly to sharpen the image. Used with the 10X and 40X objective to focus. Putting the microscope away
Remove all slides from the stage and store them properly. Raise the nosepiece to its furthest position upward Turn off the light.
Wrap the cord around the base. Secure its end. Replace the dust cover. Properly carry it back to where you got it. Be careful with slides and cover slips. They are made of glass, and if they break,
they can cut you. If you break a slide, please tell me so we can clean it up. Youre not in trouble
