    Area of Science:

    • Optics and Photonics
    • Spectroscopy
    • Holography

    Background:

    • Achieving high spectral resolution over large spectral ranges often necessitates aspheric blanks or aberrated laser sources for holographic gratings.
    • Existing methods face challenges with aberrations, particularly in far-UV applications demanding precise optical component fabrication.

    Purpose of the Study:

    • To propose a novel holographic grating configuration for improved spectral resolution and aberration correction.
    • To utilize spherical blanks, which are more amenable to fabrication constraints in the far-UV spectrum.

    Main Methods:

    • The proposed configuration is derived from an optimized holographic Rowland mounting.
    • Grating recording involves the interference of two aberrated wavefronts diffracted from concave holographic gratings.

  • Auxiliary gratings are recorded using laser point sources, with all three blanks being spherical.

    • Main Results:

    • The configuration corrects for astigmatism, coma C(1), and spherical aberration S(1), inherent to optimized Rowland mountings.
    • The proposed mounting further cancels coma C(2) and spherical aberrations S(2) and S(3) at specific spectral points.
    • The use of spherical blanks simplifies fabrication while meeting stringent far-UV optical requirements.

    Conclusions:

    • The novel configuration offers superior aberration correction compared to standard Rowland mountings.
    • This approach enables high spectral resolution over large spectral ranges using simpler, spherical optical components.
    • The method is particularly advantageous for far-UV spectroscopy where fabrication precision is critical.
