 Comments:

  • ΔF in material is n  times larger than in air, where n  is refractive index of the material:
      - n  ≈ 1.76 for sapphire,
      - n  ≈ 1.5 for glass,
  • the foXXus objectives create 1, 2 or 4 foci along the optical axis,
  • compensation of spherical aberration induced by focusing inside bulk material,
  • the crack inside material is typically longer than ΔF defined by optical design,
