Fraunhofer telescope
WebA brass 3 ½" refactor telescope by Utzschneider & Fraunhofer of Munich, circa 1825. With rack and pinion focusing, and star finder-scope. Rack and pinion motion for the altitude, and shaft driven key for slow motion in the azimuth. Mounted on a weighted pillar and claw library tripod, with folding feet. Signed: Utzschneider u. Fraunhofer in ... WebDIFFRACTION. According to the Huygens' principle, every wavefront point is a source of secondary spherical wavelets, which spread out in the direction of propagation ( FIG. 1, top/middle). This constitutes a micro-structure of energy field propagation, with the energy advancing in the direction of the wavefront, but also spreading out in other ...

The reason is obvious: there is four optical surfaces, whose synergistic effect needs to correct both monochromatic and chromatic aberrations. Follows one possible solution. The goal here is a coma-free air-spaced doublet achromat (contact type), also corrected for spherical aberration. canada oas supplement amountAll refracting telescopes use the same principles.

The objective in a refracting telescope refracts or bends light. This refraction causes parallel light rays to converge at a focal point; while those not parallel converge upon a focal plane.
