Gratings for Space-Flight

Space qualified and TRL9

À¶¾¨ÌåÓýÖ±²¥ 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, À¶¾¨ÌåÓýÖ±²¥ 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. À¶¾¨ÌåÓýÖ±²¥ Scientific gratings (master and replica) have been space qualified and are TRL9.

  • Master or Replica gratings
  • Holographic or ruled (Echelle)
  • Transmission or reflective gratings
  • Groove density : up to ~6000gr/mm
  • Various substrate shape : plane, spherical, free-form
  • High efficiency and very low stray light
  • Spectral range : from soft X-Ray to MIR (different coatings)
  • Groove shape for low polarization dependence : lamellar, blazed

 

To help us to check the feasibility of your grating, please share the grating specifications :

  • Substrate material
  • Substrate size
  • Useful area
  • Substrate shape (plane, spherical, …)
  • Groove density : constant or VLS
  • Spectral range
  • Angle of incidence
  • Diffraction order
  • Expected efficiency
  • Coating
  • Environmental conditions
