Methodology of camera spectral response measurement
Melich, Radek ; Václavík, Jan ; Žídek, Karel
Spectral response of the camera will be measured using monochromator in conjunction with an integration sphere. Camera without objective will be placed in one port of the integrating sphere and light beam from monochromator will be fed into perpendicular port. Sensor of the camera sensor will be therefore uniformly illuminated by diffused light from monochromator. Proposed FWHM of the monochromator is 15 nm as a trade-off between light intensity provided by monochromator and deformation of spectral characteristic (Picture XY). Diameter of the integrating sphere has to be larger than 100 mm to ensure uniform illumination over sensor area.

Melich, Radek ; Rail, Zdeněk ; Šípová, Gabriela
The aim of the work is mastering of S-FPL53 material machining with respect to the optical surface shape accuracy and to minimize the surface microroughness.
Aspheric lenses test report
Lédl, Vít ; Melich, Radek ; Procháska, František ; Steiger, Lukáš ; Chiarini, M. ; Cibin, L.
The scope of the document is to report the results of the tests on each of the 16 Aspheric Lenses + the 4 spare Aspheric Lens. \nIn particular, the tests performed on each lens are: reflectance of the coating on both the Aspheric Lens faces, interferometric profile of the Aspherical face and of the Spherical face of the Aspherical Lens.
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.
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.
