Lab 5: Basic Microscopy (Virtual) Grading: Divide number incorrect by total number of questions (22) Introduction: Microscope Use and Care Using the microscope is one of the most important tools a scientist has. And the most common type of microscope used is the compound light microscope. It uses several lenses and light to view specimens. It is especially useful in viewing stained specimens, ones that have a dye added to enhance the contrast of the image. The compound light microscope is very powerful, yet relatively robust and takes up little space. It can magnify images up to 1000 times their normal size! The first microscopes were invented hundreds of years ago, but it wasn’t until the 1600’s that they became popular, and the early version of the modern compound light microscope was invented. However, most folks are often confused by the type of image formed by the compound light microscope because most of the images seen in textbooks and online are from electron microscopes. Electron microscopy allows for even more powerful magnification and can be used to create 3D images or to see the internal details of a specimen. The figures shown below represent images from electron microscopes. Figure 3. Mosquito head, Scanning Electron Microscope image Figure 4.
