OPTICAL DIE WITH VARIABLE REFRACTIVE INDEX, ADAPTIVE OF ANGLE OF INCIDENCE, AND METHOD OF FABRICATING SUCH A DIE |
摘要 |
An optical die, which is intended to be placed in front of an optical sensor of a semiconductor component, has an optically useful zone having an optical axis and exhibiting a variable refractive index. Specifically the refractive index of the die is variable in an annular peripheral zone lying between a radius Ru enveloping the useful zone and a smaller radius Ro. The index is varies as a function of radial distance from a higher value near the smaller radius Ro to a lower value near the radius Ru. The function of the variable refractive index lies between a maximum and minimum profile.
