Method of Manufacturing an Optical System

A method of manufacturing an optical system (OS), the optical system (OS) being identified by a function (OF), the optical system (OS) comprising a first part (F1) defined by a first equation (EF1), EF1(x,y,z), which defines opto-geometric properties of part F1 at a spatial location defined by coordinates x, y, and z, and a second part (F2), defined by a second equation (EF2), EF2(x,y,z), which defines opto-geometric properties of part F2, where the first part (F1) and the second part (F2) are a volume or surface of the optical system, (OS), the method comprising:

• a first providing step that provides the first equation (EF1), EF1(x,y,z), said first equation (EF1), EF1(x,y,z) defining opto-geometric properties of the first part (F1) of the optical system (OS);
• a second providing step that provides the function (OF), said function identifying the optical system (OS), said second providing step comprising:
• a generating sub-step (GEN), in which a virtual optical system (VOS) calculated and generated by a computer is used to generate a virtual function (VOF) calculated and generated by a computer;
• then
• a modification sub-step (MOD), in which the virtual function (VOF) is modified to obtain the function(OF);
• and
• a calculation step (CAL), in which the second equation (EF2) is calculated from the function (OF), and the first equation (EF1);
• a first manufacturing step (M1) in which a semi-finished optical system (SFOS) comprising the first part (F1) is manufactured so as to obtain a manufactured semi-finished optical system (MSFOS);
• and
• a second manufacturing step (M2), in which the manufactured semi-finished optical system (MSFOS) is manufactured so as to be further provided with a second part (F2) defined by the second equation (EF2) and to obtain the optical system (OS).
