Abstract
There is provided a solid immersion lens in a material of refractive index n1, having an effective dioptre () separating from a medium of refractive index n2, an optical axis, a virtual object focal point for a convergent optical beam entering the lens via the effective dioptre, this virtual object focal point being conjugate with a real image focal point. The dioptre () is defined by the equation √{square root over (x+y)}−n√{square root over ((x−a)+y)}=L, x, y are the coordinates of a point (I) of the dioptre () in a system (A, x, y) whose origin is the virtual object focal point (A) and whose abscissa axis is the optical axis (Ax), Particular application to reading, writing, reproduction of optical data.
