Tunable-Blaze Diffraction Gratings for EUV Applications
Developed
in collaboration between SOLEIL and HORIBA Jobin Yvon, the Variable Groove
Depth (VGD) diffraction grating is a holographic ion-etched grating with
a continuously-variable groove depth. By simply translating the grating
parallel to the groove direction, the variable groove depth enables continuous
blaze adjustment when the VGD is illuminated with a narrow beam. The first
prototype fabricated by HORIBA Jobin Yvon was tested successfully in December
2003 on the calibration beamline at LURE before the shutdown.
VGD gratings are optimized for the new generation of synchrotron light sources. The low divergence of the beam combined with the tuneability of the VGD grating provides a unique opportunity to scan ON BLAZE, maintaining optimum efficiency over a wide spectral range with only ONE grating. Most of SOLEIL's XUV monochromators have been designed to exploit the VGD potential (Beamlines: TEMPO, CASSIOPEE, PLEIADES. etc.)
To replace several standard grating with a SINGLE VGD GRATING, please contact your HORIBA Jobin Yvon representative now.
