Abstract

We summarize the performances measured at room temperature and in cryogenic conditions of a set of NIR Volume Phase Holographic Gratings (VPHGs) which can then be used in astronomical instrumentations. VPHGs are novel optical components which can replace standard transmission gratings. Instead of a surface modulation a diffraction index modulation printed in a volume of material generates the diffraction according to the required specifications. Results on transmission and wavefront deformation are presented and compared in the two temperature regimes. These results were achieved along the run of the Joint Research Action 6 of OPTICON FP6 programme whose participating institutions are Osservatorio Astronomico di Brera (INAF), Instituto de Astrofísica de Canarias, Centre Spatial de Liège, Politecnico di Milano and European Southern Observatory.
