2 MICROSCOPES One of the most important inventions in the advancement of Biology 1. Simple Microscopes ie. magnifying glass, stereoscope (dissecting scope) have a single lens or a pair of lenses combined uses reflected light = light rays shone on an object are refracted (spread) as they pass through the convex lens(es) = enlarges object used for low power magnification of a sample image is 3 dimensional
3 2. Compound Microscope has 2 separate lenses: ocular (monocular / binocular) & the objective uses transmitted light = light passes through the object on the slide and is focused by the 2 lenses (mirrors help) Magnification = how many times the specimen has been enlarged Eyepiece x Objective = Total Magnification 10 x 40 = 400x Resolution = how clear the image is : as magnification increases, clarity decreases = stains and reducing light intensity are often used to make structures easier to see Field of View = is the diameter of the circle of light - varies depending on the microscope used & objective lens that is in place - measured in m ( 1 mm = 1000 m)
4 Care and Use of Microscopes 1. Always use both hands to carry the microscope; one on the arm, the other supporting the base. 2. Use only lens paper to clean the lenses. 3. Coarse focus knob is ONLY used when the Low (Scanning) power objective is in place. 4. Do not remove any parts. 5. When finished, make sure the Low (Scanning ) power objective is in place and the stage is completely lowered. 6. Wrap the cord around the arm and replace dust cover. Trouble Shooting Occasionally you may have trouble with working your microscope. Here are some common problems and solutions. 1. Image is too dark! Adjust the diaphragm, make sure your light is on. 2. There's a spot in my viewing field, even when I move the slide the spot stays in the same place! Your lens is dirty. Use lens paper, and only lens paper to carefully clean the objective and ocular lens. The ocular lens can be removed to clean the inside. The spot is probably a speck of dust. 3. I can't see anything under high power! Remember the steps, if you can't focus under scanning and then low power, you won't be able to focus anything under high power. Start at scanning and walk through the steps again. 4. Only half of my viewing field is lit. You probably don't have your objective fully clicked into place..

6 Guidelines for Microscope Drawings 1. Always use pencil and draw on 8 x 11 white paper portrait direction. 2. List Name, Date, Class, Group members in upper right hand corner. 3. Drawings must be large (no more than 2 per page), and single sided. 4. Drawing should be centered or slightly to the left. 5. Uses smooth, firm lines no sketching or shading. 6. Use parallel lines drawn with a ruler to label. 7. Label on the right side only; line up labels vertically. 8. Print labels in lower case letters. 9. Print a title that is precise and descriptive above the drawing. 10. Calculate the size of your specimen below your diagram. To calculate the size of the specimen Size of Specimen = Diameter of the field of view # of Times the Specimen fits Across BE SURE YOUR FINAL ANSWER IS IN m 3000 m = 100 m 30
