Since recent blazed gratings with very shallow blaze angles are technically feasible. This offers the opportunity to explore the keV-x-ray range with gratings. A grating with 200 l/mm and a blaze angle of 0.28 deg. has been manufactured by the Carl Zeiss Company and measured with synchrotron radiation from 1.7 keV to 9 keV at BESSY. The measurements have been performed for different angles of incidence for the lowest diffraction orders. A first order efficiency of up to 40 % can be observed at 2 keV. Even at 8 keV an efficiency of 15 % has been measured which is twice the value obtained from calculations. The latter indicates a lack of the computer code for the higher keV-range.
