  • Upgrade Your Optical Finder - Astronomy Hacks [Book]

    A straight-through finder is simply a standard refractor with the eyepiece in-line with the optical axis of the scope. This is the traditional finder style, and it is the type of finder supplied with most scopes. A straight-through finder produces an image that is inverted but correct left-to-right, as shown in Figure 4-23. That means you can ...

  • Lasers: Understanding the Basics

    This unique axis with very high optical gain becomes also the direction of propagation of the laser beam. A somewhat different example of a uniquely long (and flexible!) gain axis is the fiber laser. Figure 2. In the prototypical gas laser, the gain medium has a long, thin cylindrical shape. The cavity is defined by two mirrors.
