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.
Processes which control the Earth’s Temperature
Oupický, Pavel
There are discussed in this paper some of natural processes which control the temperature of Earth and they are explained and confronted with climate models Daisyworld, Greenhouseworld and Moses. There are presented also the results from the measuring of plant reflectivity with spectroradiometer
The Merz objective 160 / 179 of refractor of Upice Observatory
Rail, Zdeněk ; Šrajer, Bohdan ; Lédl, Vít ; Jareš, Daniel ; Oupický, Pavel ; Melich, Radek ; Melich, Zbyněk
In this paper, basic optical characteristic of historic objective lens manufactured by Merz are presented. This objective lens has been in use in main dome of Upice observatory since 1960. The lens was cleaned up and adjusted, during reconstruction work of paralactic mount in beginning of this year. Opto-mechanical parameters of the lens were measured. Measured values of optical parameters are presented.
The use of fibre spectrometers in the natural sciences
Oupický, Pavel
This artical informs briefly about fibre spectrometers and about their using in the physics, meteorology and in the botany by the measuring of sun radiation and its reflexion with plants.

Melich, Zbyněk ; Melich, Radek ; Oupický, Pavel ; Šolc, Ivan ; Klimeš st., J. ; Klimeš ml., J.
Šolc birefringent polarizing filter for more spectral lines Šolc birefringent polarizing narrow - bandpass filters are successfully used for professional observations of solar chromosphere. They are usually constructed to work for only one transmitting wavelength. Principally it is possible to design such filters to transmit more narrow – banded spectral lines. Filter consist of two parts: Frontal part is broad – band filter, with which, required spectral line can be adjusted. Second – main part consists of 26 quartz plates. Filter is designed for observation of Sun in interesting spectral lines: KII, HY, BaII, HZ, D1, D3 and He.
The measure device for measuring and control of light conditions of plant growth
Oupický, Pavel
This report describes the special radiometers for the measurement of light condition for plant growth, which were developed in the Optical Development Workshop of AS in Czech Republic. It was published on the conference with international participation called „The man in his terrestrial and space environment“ which took place in th Upice town 2005 year.
