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,
