Paper Abstract

Our OPTICON JRA6 research line developed a 4 year study of non conventional uses of Volume Grating Holographic Gratings (VPHG). The final results are witnessed by the construction of a bench prototype of tunable grating and a tunable filters. This realization has all the characteristics of robustness and versatility to be worth extending its use to existing of future FOSC camera spectrograph. The adjustable bending of the in/out-coming beam allows broadband VPHG to exploits the superblaze efficiency curve in dispersing mode and thick grating, to act as narrow passband filter.
