Lenes Telescope Zoom - HOME Lenes Telescope Zoom Unusual Telescopes by Peter L. Manly, X In this book, Peter Manly surveys more than 150 unusual telescope designs. These are telescopes built by amateur and professional astronomers to suit some special need. There is, for instance, an inflatable telescope and one with a liquid mirror. Every so often a neglected design comes back into fashion: the largest telescopes now under construction use the alt-azimuth design that was ignored for over a century, and liquid mirror telescopes can be used for zenithal astronomy. The author shows why a ...

There are several different designs with slightly different characteristics. Quadruply clad fiber - In fiber optics, a quadruply clad fiber is a single-mode optical fiber that has four claddings. Each cladding has a refractive index lower than that of the core. Optical fiber - An optical fiber (or fibre) is a transparent thin fiber, usually made of glass or plastic, for transmitting light.
