Microscopes and Microscopy
The purpose for including a lab on microscopy in his course is because it is a very important tool in making detailed observations. This lab helps the average person realize that there is much more to things than what you see with the naked eye. In the field of human biology microscopes are very important for many reasons. In the late 1500’s a scientist named Zacharias Janssen created the first microscope of it kind and now we have several microscopes that are very important to the study of human biology. The compound microscope is used to view individual cells as well as living cells such as hair. Electron microscopes can be used to view things such as biological tissues and organisms. Also, another popular microscope used in human biology is the stereo microscope, which is commonly used to dissect and examine human tissue.
When studying the “optics” slide in the interactive section of this lab it displayed image orientation. To display this it took the letter “e” and showed you the standard view to the naked eye and then it showed you the view through a light microscope and it looked very different. The “e” was upside down and backwards left while looking down in the microscope. The reason it looked like this was because of the shape and lenses in the microscope.
While studying the color threads on the interactive microscope you notice that the colors are red, green, and yellow from top to bottom. The magnification that was useful in helping me determine the order was 400x. This magnification allowed me to see that the yellow color thread was on the bottom and that the green color thread was in the middle. The optical principles that are in play here are perfect lens characteristic and transmitted light microscopy optical pathways.
Interpupillary distance is the distance between the centers of the pupils of the two eyes. The way to determine what the interpupillary distance is with a device...
