Gratings for Space-Flight

Space Flight Diffraction Grating

Space qualified and TRL9

HORIBA Scientific (with its Jobin Yvon Grating Technology) has 50 years of experience in space-flight gratings. The first space flight ruled gratings were produced for the CNES mission D2A in early 70’s. Since that date, HORIBA Scientific has continuously produced some of the most technically-challenging gratings ranging from off-plane X-ray replica gratings to aspherical 5800gr/mm VLS gratings for the FUV and Transmission Grisms or very low groove density VNIR-SWIR ruled blazed gratings. HORIBA Scientific gratings (master and replica) have been space qualified and are TRL9.
