Oprava objektivu 160/2500 turnovské hvězdárny
Rail, Zdeněk ; Melich, Zbyněk ; Šrajer, Bohdan ; Šípová, Gabriela ; Kaucká, Iva ; Franců, Helena ; Melich, Radek
Tento referát přináší informace o opravě achromatického objektivu o průměru 160 mm a ohniskové vzdálenosti 2500 mm, vyrobeného v 70. letech ve Vývojové optické dílně ČSAV v Turnově. Refraktor s tímto dubletem se stal hlavním přístrojem místní hvězdárny. Spojka tohoto objektivu obsahovala šlíry a bylo ji nutné vyrobit novou
Reflectivity of a mirror in XUV spectral region (46.9 nm).
Schmidt, Jiří ; Koláček, Karel ; Štraus, Jaroslav ; Frolov, Oleksandr ; Prukner, Václav ; Melich, Radek ; Psota, Pavel ; Sobota, Jaroslav ; Fořt, Tomáš
A focusing mirror as an optical element is used in our applications that require light collection (e.g. for laser ablation studies). A knowledge of the mirror reflectivity is important for determination of focused laser pulse energy, or for determination of local fluencies near the laser focus. The reflectivity of our spherical focusing mirror with(/without) multi-layer coating was measured. Reflection coefficients of this mirror in a long period of time are also reported. Further, the incidence-angle dependence of the XUV reflectivity of flat mirrors is presented as well.

PROBA3 Coronograph System Progress Report
Horodyská, Petra ; Melich, Radek
The scope of this document is to provide to CSL and ESTEC a progress report of ongoing activities as described in Project Management Plan v1_1. TOPTEC main activities cover realization of coronagraph optical elements, housing for this elements, HDD and the Lyot stop realization. In year 2016, the DM model was finished and delivered and the STM model was competely realized and delivered. Toptec started to prepare the documents for Critical Design Review (CDR).
Device calibration.
Melich, Radek ; Václavík, Jan ; Žídek, Karel
The device has to be calibrated in absolute terms for its brightness response. This will be facilitated by a combination of an integrating sphere and collimating objective. The emitted total light intensity will be controlled by a reference photodiode inside the integrating sphere.
