Diffractive-refractive optics: low-aberration Bragg-case focusing by precise parabolic surfaces

Based on analytical formulae calculations and ray‐tracing simulations a low‐aberration focal spot with a high demagnification ratio was predicted for a diffractive–refractive crystal optics device with parabolic surfaces. Two Si(111) crystals with two precise parabolic‐shaped grooves have been prepa...
