Thin Lenses and Ray Diagrams - ScienceDirectMichael P. Keating Ph.DGeometric, Physical, and Visual Optics (Second Edition)
Here are two examples to help practice drawing ray diagrams for concave lenses. Examples Ray Diagrams for a Concave Lens Example 1 A pencil is placed {eq}20\ \mathrm{cm} {/eq} away from a concave lens that has a focal length of {eq}-10\ \mathrm{cm} {/eq}. Draw the ray diagram...
A series of free high school Physics lectures. Related Topics: More Physics Lessons Common Core Mathematics All lenses and mirrors can use ray diagrams to find images. There are three principal rays. The first principal ray occurs when the light comes in parallel to the principle axis, it goes...
In theory, it would be necessary to pick each point on the object and draw a separate ray diagram to determine the location of the image of that point. That would require a lot of ray diagrams as illustrated below.Fortunately, a shortcut exists. If the object is a vertical line, then ...
In ray diagrams, it is automatically assumed that thin lenses are used. A thin lens is characterized by a very small diameter compared to the radii of the two surfaces. It allows the light to refract once but does not include any aberration or dispersion of light. In addition, all light ...
Figure 1. Ray diagrams illustrating how light travels through the lenses of optical instruments: (a) and (b) convex lens; (c) human eye; (d) magnifying glass; and (e) compound microscope. The power of an objective is shown by its resolution. The resolution (R) of the objective lens ...
Now we’re ready to learn how to draw the rays in our ray diagrams. For positive- and negative-powered lenses there are three rays that we need to learn, but they’re drawn slightly differently for each lens type, so I’ll start with positively powered lenses in this section and then ...

Hello, I wanted to confirm a suspicion with how the Aimpoint optics work, but to do that I need to do some ray diagrams. I only ever did them with simple convex, concave, and spherical systems while at college. From what I already know of how reflex sights work, the LED is placed ...
Ray optics of a telescope question Its an often prøven fact that a convex lens focused rays parallel with the optical axis into the focal point of the lens, but what about rays that are parallel with each other and with a small angle to the optical axis? In ray diagrams with telescop...
