Jul 19, 2010 An ultra precision large optics grinding machine, BoX , was developed and produced at Cranfield University. BoX offers a rapid and economic solution for grinding large off-axis aspherical and free-form optical components. Grinding high accuracy surfaces with low subsurface damage reduces subsequent polishing time.
With the construction of the 60-inch telescope imminent, John D. Hooker, a prominent local businessman and friend of Hale, offered to pay for the production of the mirror for an even larger instrument, an 84-inch. Hale jumped at the opportunity, and his enthusiasm prompted Hooker to raise the ante. Hale would have his mirror, but it must be 100 ...

Apr 04, 2018 New telescopes, instruments, and devices rely on such foundational materials. It's the same with Zerodur, he says, and we hope we can keep pace with technological developments. Hartmann is an author or coauthor of four papers at SPIE Optical System Design , 14-17 May in Frankfurt (Germany), including one on the mechanical strength of ...
Mirror-O-Matic grinding machine. When I decided in 2009 after a ten-year break to get into mirror making again, it quickly became clear to me that I would need to construct machine, as hand grinding big mirrors is not something very beneficial for the hands of a musician.
Amateur Telescope Making Main Page. For it is true that astronomy, from a popular standpoint, is handicapped by the inability of the average workman to own an expensive astronomical telescope. It is also true that if an amateur starts out to build a telescope just for fun he will find, before his labors are over, that he has become seriously ...

Joseph Ritter von Fraunhofer (/ ˈ f r aʊ n ˌ h oʊ f ər /; German: [ˈfraʊnˌhoːfɐ]; 6 March 1787 – 7 June 1826) was a Bavarian physicist and optical lens manufacturer.He made optical glass and achromatic telescope objective lenses, invented the spectroscope, and developed diffraction grating.In 1814, he discovered and studied the dark absorption lines in the spectrum of the sun now ...
Nov 06, 2020 Machine For Grinding Telescope Specula. Machine For Grinding Telescope Specula. W. Forgan. The simple addition to an ordinary lathe for the purpose of grinding telescope specula has been of so much benefit to the author that it was thought, if made known through the medium of the Society of Arts, it might become useful to others interested.
As a purchasing agent in the Astrophysics Machine Shop, Al Shea was thrilled by the 100-inch Mount Wilson telescope and grateful to be part of the construction of the 200-inch Palomar telescope. Every night at the supper table I would hear names like Bruce Rule, Mickey Sherburne, Fritz Zwicky, and Caltech's president, Robert Millikan.

Sep 09, 2019 Fine grinding and polishing of Segment 2 took less than half the calendar time as the same operations for Segment 1. Development of tests for the GMT off-axis segments was a major challenge. Like all modern telescope mirrors, they are measured with an interferometer and a null corrector, shown in Figure 12. The null corrector converts a ...
Mike's Telescope Workshop. I have been involved in amateur telescope making (ATM) for over 30 years. In that time I have built many different telescopes and other instruments. This web page chronicles just a few of them. ATM is a great and very rewarding hobby. You can build a better telescope than you can buy.

Nov 16, 2018 Uğur İkizler is a telescope maker in Bursa, and has made telescopes and a machine. I'm sure either of these telescope makers would help you to learn about making optics. There are others in Turkey also. Usually the same machine is used for grinding, polishing, and figuring. Types of machines: http://www.astrosurf...es-type-eng.htm. Among the machines shown, see the Elgin-Waineo machine. This is probably the most common type of machine.
