WebNov 8, 2000 · Most of the telescopes you see today come in one of two flavors: The refractor telescope, which uses glass lenses. The reflector telescope, which uses mirrors instead of the lenses. Both types … Web102 Mm REFRACTING TELESCOPE - Sep 03 2024 My first book, 'Making a Refracting Telescope', featured the making of a small refracting telescope from commonly found and inexpensive materials. The telescope had a 48mm diameter achromatic objective lens with a focal length of 450mm and was designed to be used with standard 24.5mm (0.965 inch)
Reflecting Telescopes: Explanation, Diagram, Applications
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. … See more 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 … See more Refractors suffer from residual chromatic and spherical aberration. This affects shorter focal ratios more than longer ones. A 100 mm (4 in) f/6 achromatic refractor is likely to show considerable color fringing (generally a purple halo around bright objects). A 100 mm … See more • Astrograph • Baden-Powell's unilens • Catadioptric telescopes See more • The optical work of Charles Tulley See more All refracting telescopes use the same principles. The combination of an objective lens 1 and some type of eyepiece 2 is used to gather more light than the human eye is able to collect on its own, focus it 5, and present the viewer with a brighter, clearer, and See more Refracting telescopes were noted for their use in astronomy as well as for terrestrial viewing.
