Figure 1. Rays of light entering a converging lens parallel to its axis converge at its focal point F. (Ray 2 lies on the axis of the lens.) The distance from the center of the lens to the focal point is the lens’s focal length f. An expanded view of the path taken by ray 1 ...
element whose number of pixels is large while securing compact constitution such as five lenses by setting space between a 1st lens and a 2nd lens constituting a front group to a specified long distance and making the surface of the 2nd lens on an object side a surface having large curvature...

Microscope - Image Formation, Optics, Magnification: The objective collects a fan of rays from each object point and images the ray bundle at the front focal plane of the eyepiece. The conventional rules of ray tracing apply to the image formation. In th
Step 1. Examine the situation to determine that image formation by a mirror is involved. Step 2. Refer to theProblem-Solving Strategies for Lenses. The same strategies are valid for mirrors as for lenses with one qualification—use the ray tracing rules for mirrors listed earlier in this secti...
