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).

One of the effective method of improving diamond tool life on rulling large diffraction gratings is developing precise double-cone edged on line edge transfering tool. But traditional died weight or manual lapping technique couldn't meet the precision requirement of on line edge transfering tool. So preliminary studied rigid lapping of diamond grating ruling tool. Choosing traditional BC6063 shaping machine and made a series of alteration on it  achieved the automation of lapping process of diamond grating ruling tool. Through lapping grating ruling tool and AFM measurement find that the surface roughness of tool is 1.51nm  the radius of tool edge is 160nm  edge quality is good enough  this verified the feasibility of rigid lapping of diamond grating ruling tool and lay the foundation for developing precision lapping machine.
