The lens is a transparent biconvex structure in the eye that, along with the cornea, helps to refract light to be focused on the retina. By changing shape, it functions to change the focal length of the eye so that it can focus on objects at various distances, thus allowing a sharp real image of the object of interest to be formed on the retina ...

Now that we know a bit about the history of microscopy, let's dig into the first form that existed, light microscopy. This is the form that is familiar to most of us, as the microscopes we all looked through in high school biology class were light microscopes. How do these work, what can we do with them, and how does one operate a light ...

This is an example of a ray diagram for a double lens system in which the image from the first lens is "downstream" from the second lens. This is the case in which the image from the first lens serves as a "virtual object" for the second lens. For the first lens, the object distance and image distance are positive. If the 2nd lens were not ...
