FISHER PRICE my first electron microscope

An electron microscope bombards the surface of a specimen with, you guessed it, electrons, and then measures the energy of the reflected electrons to create a topographical image of a sample. The microscope used for the teaching purposes of the class I am taking was built in, like, 1978, so there is a nob for everything. I wish I could show you a picture but they are so old that google images does not have one. The item I imaged was this:<br><br><img src="http://i143.photobucket.com/albums/r134/aclauer/pii.jpg"></font> The area marked 1 is what these images are of. It is the contact for this card when it is inserted into a board. I will be imaging areas 2 and 3 as well, but I am starting with 1. The first image I took was at 15x magnification:<br><img src="http://i143.photobucket.com/albums/r134/aclauer/15xsamp1-1.jpg"><br>Not that high mag, but exciting none the less.<br>Next was 50 mag I think.<br><img src="http://i143.photobucket.com/albums/r134/aclauer/50xsamp1-1.jpg"><br>Notice how the silicon board area in between the contact is starting to become less of a solid area and much more wavy.<br><br><img src="http://i143.photobucket.com/albums/r134/aclauer/150xsam1.jpg"><br>I think this was 500. Check out how weird the silicon area is starting to look.<br><br>Then I did the connector and silicon individually:<br><img src="http://i143.photobucket.com/albums/r134/aclauer/500xsa1.jpg"><br>I didn't clean the specimen with alcohol before, only water so some of those artifacts may disappear. That's the connector, btw.<br><img src="http://i143.photobucket.com/albums/r134/aclauer/1500xsa1-1.jpg"><br>Thats the silicon. <br><br>Anyway, it's very exciting for me. Also, xray analysis proved that the connector is primarily gold.<br>
