We present three exponential solutions to the radiative transfer equation for polarized light (RTE). Two of them are general but with no practical application in the numerical codes as of today. The third one, while not general, presents less constraints than other well-known analytical solutions and still allows implementation in a numerical code. The performances of this code, named DIAGONAL, will be illustrated through several examples. It has been used as the core of an inversion code, some of whose preliminary results will also be presented.
