Webb5 dec. 2014 · A simple refracting telescope uses a lens as an objective to collect and focus light. Noted as the first kind of optical telescope, this technology would later soar to popularity during the second half of the 19 th century. A problem with this device, however, arose in the form of chromatic aberration. WebbThe two basic kinds of telescopes are the reflector and the refractor. Select a telescope to see the path light takes as it travels. Left hand choice: A refracting telescope works …

A refracting telescope (also called a refractor) is a type of optical telescope that uses a lens as its objective to form an image (also referred to a dioptric telescope). The refracting telescope design was originally used in spyglasses and astronomical telescopes but is also used for long-focus camera lenses. … Visa mer Refractors were the earliest type of optical telescope. The first record of a refracting telescope appeared in the Netherlands about 1608, when a spectacle maker from Middelburg named Hans Lippershey unsuccessfully tried … Visa mer Refracting telescopes were noted for their use in astronomy as well as for terrestrial viewing. Many early discoveries of the Solar System were made with singlet refractors.
