This thesis is focused on development of opto-mechanical tools and procedures, which, applied in the preparation of the new Ring Imaging Cherenkov detectors would contribute to the achievement of the best possible performance of these detectors. On the base of requirements, given by the physics objective of the LHCb detector, and an analysis of the detector opto-mechanical system, specifications of individual opto-mechanical components were determined. Spherical, eventually planar mirrors and mirror adjustable mounts were the components of interest. Next, their parameters to be characterized were defined. For mirrors, it was a radius of curvature, a precision of the geometry of reflecting surface, a spectral reflectivity and roughness of the reflecting surface and a long-term stability should have been determined. Possible measurement methods were studied and relevant set ups based on chosen convenient methods were developed. In the development, available modern metrology technologies, like laser operated instruments or digital image processing, were applied with attempt to innovative them and to increase their achievable performance limits. When applicable, the set ups were automated in order to make the measurements effective and objective. An optical laboratory, devoted to the characterization of the RICH opto-mechanical components, was established. Collaboration with industry was started. A number of prototypes of mirrors and of mirror mounts for both the LHCb and COMPASS RICH detectors was tested, and a feedback to manufacturers was provided. On the base of obtained results, manufacturers optimized their technologies, and initial specifications were modified. The quality of the whole production of the COMPASS RICH 1 mirrors was tested in the TA2 optical laboratory. The laboratory and its facilities are being applied for optimization of the LHCb RICH opto-mechanical component parameters and they will be used for quality tests of final products. The development of measurement instruments has not been finished, present set ups are being further improved and the development of new set ups is planned.
