MICROWAVE TELESCOPE, THE PARTS: * A microwave/millimeter-wave telescope can observe space objects in a frequency range between 70 and 300 GHz * some X-ray telescopes use Wolter telescopes composed of ring-shaped 'glancing' mirrors made of heavy metals that are able to reflect the rays just a few degrees.
A reflecting telescope is a telescope that uses a single or combination of curved mirrors that reflect light and form an image. The reflecting telescope was invented in the 17th century,by Isaac Newton, as an alternative to the refracting telescope which, at that time, was a design that suffered from severe chromatic aberration. Although reflecting telescopes produce other types of optical aberrations, it is a design that allows for very large diameter objectives. Almost all of the major telesco
