This paper deals with manufacturing of a positive lens of achromatic dublet. Diameter of the dublet is 158 mm and its focal length about 2500 mm. The glass material of the former lens was inhomogeneous and the dublet provided bad images. This is why we decided to manufacture new lens. The process was made by means of former machines of our workshop. The telescope with this dublet is placed at the Observatory of Turnov and serves for public astronomical observation.

The quality of the pedagogical-psychological advisory. Prevention of socially undesirable phenomena in the Ústí nad Labem region
Ulrichová, Iva ; Vrzáček, Petr (advisor) ; Slavíková, Ivana (referee)
Education is a personal and social investment, and it must be of high quality to achieve the expected economical, social, and personal progress. The education system includes pedagogical-psychological advisory services, which are aimed at helping children and adolescents to resolve problems occurring in their upbringing, education process, and employment selection. In the Czech Republic, the pedagogicalpsychological advisory is provided particularly at school age level and within school advisory departments. Unlike the quality and effectiveness of education, the quality of the advisory services, which includes diagnostics, methodology, and prevention, has never been treated with the appropriate attention. The advisory facility employees provide services for children, their parents, and for the pedagogical employees at schools. One of the tasks of the advisory facility, which is currently growing in significance, is the provision of services for the prevention of socially undesirable phenomena in children and youths. The text of this work focuses on pedagogicalpsychological counselling, its origin, development, and current status, and the evaluation possibilities regarding the advisory services. The principal task of the diploma work is to provide a perspective of the real situation of employees - the...

The Telescopes of Dall-Kirkham
Rail, Zdeněk ; Ulrichová, Iva ; Kuryshev, V. ; Vápenka, David
The paper deals with the optical aberrations of the two-mirror telescopes composed of the ellipsoidal primary and the spherical secondary mirrors. The system was discovered by Horace Dall and Alan Kirkham at the end of the Twenties of the 20th Century. Its optical elements are easy to manufacture and measure. These telescopes can be equipped by lens correctors and turned into multipurpose devices both for planetary observation and wide field photography. Several telescopes were manufactured in workshop of the Toptec Center in Turnov.
