Device calibration.
Melich, Radek; Václavík, Jan; Žídek, Karel
2016 - English
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. Keywords: absolute brightness calibration Available at various institutes of the ASCR

Selection process of an observation objective with respect to minimal glare level
Melich, Radek; Václavík, Jan; Žídek, Karel
2016 - English
An observation objective (OO) that will image the projection screen on the camera detector is necessary to choose in a such a way that its glare performance is traced. This objective feature is not documented by an objective supplier, therefore we design a procedure that enable us to relatively compare the objective between each other. Keywords: objective glare Available at various institutes of the ASCR

Optimalizace a testování ITO vrstev
Hlubuček, Jiří
2016 - Czech
Všechny depozice ITO probíhaly za pokojové teploty na BK7 substrát tloušťky 80 mm. Během, někdy i po depozici, se teplota v komoře mírně zvyšovala především při použití asistenčního děla, nikdy však nepřesáhla 40 °C. Rychlost odprašování je relativně vysoká, proto byly použity relativně nízké výkony primárního iontového děla (KDC). Optimalizovala se příprava bez i s použitím asistenčního iontového děla (IBAD) s kyslíkovým nebo kyslíkovo-argonovým výbojem. Rychlost depozice určena podle krystalového monitoru (CRY), reálná se mírně liší podle typu depozice. Tloušťky vrstev určeny na základě měření elipsometru. Odpor měřen přiložením kontaktů na okraje vzorku v prostředku podél homogenní tloušťky vrstvy. This report deals with ITO (indium tin oxide) deposition by ion-beam sputtering, and was custom-made for Crytur. All the depositions were performed at room temperature (i.e. without heating). Optimalization of ITO thin films was made without as well as with the assistant ion beam using oxygen or argon-oxygen discharge. Deposition rate was tracked in-situ by quartz crystal monitor. More precise determination of the film thickness was made after deposition by spectroscopic ellipsometry. Electrical resistance was also evaluated.\n Keywords: ITO; IBS; IBAD; sputtering process development Available at various institutes of the ASCR
