A new Aperture Centring Device (ACenD) for precisely positioning small apertures with respect to the autocollimator's optics has been developed. With the new device, differences in the angle response of autocollimators between the calibration at a la

Interpolation errors at small angular scales are caused by the subdivision of the angular interval between adjacent grating lines into smaller intervals when radial gratings are used in angle encoders. They are often a major error source in precision

The performance of x-ray beamlines at 3rd generation synchrotron radiation sources and Free Electron Lasers (FELs) is limited by the quality of the state of the art optical elements. Proposed FEL beamlines require optical components which are of bett

The technological limit on the beam quality when modern synchrotron radiation sources are used is determined by the geometrical accuracy of the optical components. This in turn is limited by the accuracy of the measuring technique which is within the

Calculations of the waveguide mode coupling losses due to free space propagation between the waveguide endings and the resonator mirrors of a coaxial Cu-waveguide are presented. The results show that the mode coupling losses have a strong influence o

A coaxial carbon-dioxide waveguide laser with rf excitation at 96.5 MHz and an output power exceeding 1.3 kW is described. This laser uses a new concept of electrode segmentation for discharge homogenization in addition to a new kind of optical reson
