Abstract:

A technique for aligning and calibrating spectrographs with the cross-dispersion of ultraviolet and vacuum ultraviolet (VUV-UV) ranges using an additional holographic diffraction grating operating in the visible region of the spectrum is presented. This holographic diffraction grating provides a spatial position of the diffracted radiation at a selected wavelength in the visible range, which matches the position of the diffracted VUV-UV radiation when mounted in the scheme of a ruled operating grating. The efficiency of this technique is demonstrated by performing the alignment and calibration of two VUV-UV channels of the ground-based simulator of a three-channel space spectrograph, which was developed in the framework of the project Spectrum-UV (World Space Observatory).
