In ultraviolet spectroscopy  groove irregularity and surface roughness of nanometer magnitude can cause a significant loss of diffraction efficiency. Therefore  there is a constant need to improve the diffraction efficiency. A blazed grating can concentrate most of the light intensity into a desired diffraction order  it is important to control the groove shape precisely  so it is the optimum choice among gratings of different kinds of profile. As the operating wavelength of most UV spectral applications is less than 200 nm  especially the blaze angle and the apical angle. We have presented a direct shaping method to fabricate EUV blazed gratings by using an ion-beam mixture of Ar+ and CHF2 +to etch K9 glass with a rectangular photoresist mask. With this method  the required blaze angle is small  we have succeeded in fabricating well-shaped UV blazed gratings with a 1200 line/mm groove density and 8.54 blaze angles and 1200 line/mm groove density and 11.68 blaze angles  and the metrical efficiency is about 81% and 78%. The good performance of the gratings was verified by diffraction efficiency measurements. When one uses the etching model  the conditions on the ion-beam grazing incident angle and the CHF3partial pressure should be noted. Besides  since the etched groove shape depends on the aspect ratio of the photoresist mask ridge  if we wish to fabricate larger gratings with this method  we must improve the uniformity of the photoresist mask before ion-beam etching. 2011 Copyright Society of Photo-Optical Instrumentation Engineers (SPIE).

A brand-new technology for manufacturing SiC reflecting mirror that is different from the traditional method is adopted  which is called as fixed abrasive surfacing technology. Not only the new method achieves better mirror quality with bigger diamond in diameter quickly  but also because of the fixed motion between the abrasive and workpiece and it will be good for surface finishing. During experiment  material removal characteristic which is on SiC under certain rotation speed and pressure by W7  W5  W3.5  W1.5 pellets has been tested. Through those removal curves  we come to a conclusion that the technology not only has a higher removal rate  but also has much more stability. In addition  the surface roughness experiment is mentioned. In the first stage  we achieved a mirror with surface roughness 42.758nm rms with W7 pellets. The surface roughness is descending as we change pellets with smaller diamond in diameter . At the end of experiment  a smooth surface with roughness 1.591nm rms has been achieved after using W1.5 pellets. Experiment results indicate that the technology which manufactures SiC reflecting mirror with fixed abrasive is able to replace the traditional slurry abrasive completely in certain finishing phase and also has a great foreground in application. 2009 SPIE.

A soft x-ray reflectometer with laser produced plasma source has been designed  which can work from wavelength 8nm to 30 nm and has high performance. Using the soft x-ray reflectometer above  the scattering light distribution of silicon and zerodur mirrors which have super-smooth surfaces could be measured at different incidence angle and different wavelength. The measurement when the incidence angle is 2 degree and the wavelength is 1 lnm has been given in this paper. A surface scattering theory of soft x-ray grazing incidence optics based on linear system theory and an inverse scattering mathematical model is introduced. The vector scattering theory of soft x-ray scattering also is stated in detail. The scattering data are analyzed by both the methods above respectively to give information about the surface profiles. On the other hand  both the two samples are measured by WYKO surface profiler  and the surface roughness of the silicon and zerodur mirror is 1.3 nm and 1.5nm respectively. The calculated results are in quantitative agreement with those measured by WYKO surface profiler  which indicates that soft x-ray scattering is a very useful tool for the evaluation of highly polished surfaces. But there still some difference among the results of different theory and WYKO  and the possible reasons of such difference have been discussed in detail. 2009 SPIE.
