We demonstrate a dual-optic imaging-spectrometer for high harmonic generation sources, ideal for coherent diffractive imaging in a tunable monochromatic mode. Our optimization combines record-high efficiency, high spectral resolution, low aberrations, broad spectral coverage, and polarization-maintaining.
