Design of a mirror collimator for a light beam outgoing from a silica fibres bundle of a circular cross section.
 Vodák, Jiří ; Brillová, Kateřina (referee) ; Ohlídal, Miloslav (advisor)
Imaging spectroscopic reflectometry is an innovative method for studying optical properties of thin layers. This method allows as studying large areas of thin layers. Imaging spectrophotometer designed in The Institute of Physical Engineering was supposed to allow measurements along areas of about 25 mm x 25 mm. However this area was not achieved. To achieve desired dimensions of the area under study it is necessary to redesign the optical transmission setup between a source of monochromatic light and the imaging spectrophotometer.The old spectrophotometer design consists only of a mirror collimator not sufficient enough to collimate a rectangle shaped light beam on the output of the monochromator. The new design will consist of optical cable of silica fibers transforming the rectangle input light beam into a light cone which will be easier to collimate by a mirror collimator.
