SEM Microscope Page

While studying Ethan Allen Park we collected of samples that we would later examine with a scanning electron microscope (SEM). An SEM is a microscope that uses a beam of electrons to scan an object and produce an enlarged image of it on a cathode-ray tube.  It can work at much greater magnifications than a light microscope and allows one to see the exterior of the sample. In order to allow the samples to reflect electrons properly, they are coated in a conductive metal, which usually includes gold. The below pictures are SEM Polaroid photos of the various samples we collected. They included a mosquito, lichen, and various other biota, however, only mosquito photos are pictured below.
