The Digitalisation of the Maksutov Camera 350/840 of the Observatory in Úpice
Melich, Zbyněk ; Rail, Zdeněk
The Maksutov chamber with a diameter of 350 mm and a focal length of 840 mm was manufactured in Turnov in the early 1980s. At the Úpice Observatory it was used to photograph the sky for photographic film. Currently, we have been asked to convert it to a digital device. It was necessary to design and manufacture a correction element for the chamber to straighten its focal surface and to equip it with a suitable digital camera. In this work we present description of modification of this device.
The Residual Optical Aberrations of the Merz Objective Lens 108/1620 mm
Melich, Zbyněk ; Rail, Zdeněk ; Vápenka, David ; Šrajer, Bohdan
During the cleaning and adjustment of the Merz lens with a diameter of 108 mm and a focal length of 1620 mm, we had the opportunity to measure its optical parameters. From the measured values we made a calculation of residual optical defects of this achromatic lens. The results of these mathematical simulations are presented in this paper. The lens was made around 1923.
The Repair of an Objective Lens 160/2500 of the Observatory in Turnov
Rail, Zdeněk ; Melich, Zbyněk ; Šrajer, Bohdan ; Šípová, Gabriela ; Kaucká, Iva ; Franců, Helena ; Melich, Radek
This paper brings the information about repair of the achromatic objective lens of diameter 160mm and focal length 2500mm produced by the Development Optical Workshop of the ČSAV in Turnov. The refractor with this dublet has become the main telescope of a local astronomical observatory. The positive lens contained impurities – schlieren and it was necessary to produce a new lens and change it.
The Maksutov´s Systems from Turnov
Rail, Zdeněk ; Melich, Zbyněk ; Jareš, Daniel ; Pintr, Pavel ; Vápenka, David
This paper deals of a design and a manufacture of optical systems with the entrance meniscus corrector of Maksutov. Many of these high performance systems have been manufactured in several workshops in Turnov since Seventies. We present our experience with the optical design, manufacture and construction of the meniscus telescopes and cameras in this article.
The Simulation of Residual Optical Aberrations of the Objective Lens of Merz 124/1477
Rail, Zdeněk ; Melich, Zbyněk ; Šrajer, Bohdan
This objective lens was renoved in the Institute of Plasma Physics, v.v.i. Center Toptec in Turnov. During the process we got a possibility to measure the objective lens on the optical bench and to evaluate its residual optical aberrations. The objective lens was manufactured in 1860-1870 years
The Optical Parameters of Objective Lens Secrétan Paris 130/1930 of Observatory of Úpice
Rail, Zdeněk ; Melich, Zbyněk
The Optical Parameters of Objective Lens Secrétan Paris 130/1930 of Observatory of Úpice Objective lens of Secrétan Paris 130/1930 of Úpice observatory was cleaned a measured its optical parameters in IPP AS CR, v.v.i. - TOPTEC. In this paper we present results of mathematical simulation of residual aberrations of this lens.
The Catadioptric System of G.M. Popov of the Observatory of Úpice
Rail, Zdeněk ; Melich, Zbyněk
During the Sixties of the Twentieth Century series of two-mirror catadioptric telescopes were designed with a correcting lens in front of their secondary mirror. One of the first designers of these devices was P.P. Argunov. His optical designs were further developed by G.M. Popov, J. Klevcov and other opticians. In 2005 one telescope of a Popov system of diameter 305 mm was manufactured in the Development Optical Workshop of Academy of Sciences of Czech Republic /now Institute of Plasma Physics of AS CR,v.v.i.-Toptec/ in Turnov. The telescope was intended to substitute an older Maksutov-Cassegrain telescope of diameter of 260 mm of the Observatory in Úpice which required the reconstruction. In this paper we present an optical design of the Popov´s system of the Observatory in Úpice and compare it with an equal commercial Schmidt-Cassegrain telescope and further devices.\n
History of development of X-ray optics in Czech Republic
Inneman, A. ; Pína, L. ; Hudec, René ; Černá, D. ; Maršíková, V. ; Melich, Zbyněk
The summarizing paper sums up more than 40 years of research and development of grazing incidence X-ray optics in the Czech Republic. The origin of astronomical X-ray optics is related to spaceInterkosmos programme Interkosmos. Overall sixty pieces of Wolter I X-ray objectives were manufactured in key cooperation with the Optical Workshop of the Academy of Science in Turnov. Eight of them were used in four different space missions. After the end of Interkosmos project the development of X-ray optics was reoriented to X-ray laboratory tools for crystallography, to Lobster eye systems for wide-angle space monitoring and to Kirkpatrick-Baez imaging system for large X-ray space telescopes. At present, the novel concepts and technologies for X-ray space telescope considered in future ESA, NASA and JAXA missions are being developed
The improvement of resolving power of small chromospheric telescopes
Melich, Radek ; Rail, Zdeněk ; Melich, Zbyněk
The Mersen system was constructed for improvement of resolving power of commercial solar chromospheric telescopes (Coronado, Lunt). Former device of aperture of 40 mm and resolving power 4“ was equipped with entral member – afocal Mersen system of 120 mm diameter. Resolving power of composed systém was increased to 1.2“ which was observed during good seeing conditions.
Optical design of imaging system of spectrograph with multichannel filter
Rail, Zdeněk ; Jareš, Daniel ; Lédl, Vít ; Melich, Radek ; Melich, Zbyněk ; Václavík, Jan ; Oupický, Pavel
At present time multi channel filter is developed within grant in IPP AS CR, v.v.i. It will enable to observe solar phenomena in several interesting working wavelengths. This filter is composed of five members and possesses long optical interval of parallel beams. In this paper we present several variants of imaging systems of spectrograph which are optimized for this filter.
