The mechanical stress birefringence (SBR) has received attention due to its effect on polarization in immersion lithography. In this paper, we present a strict mathematical model to obtain the correct SBR and slow-axis distributions of optical plates. First, the linear conditions of the model are solved to ensure the reasonable assembly of optical plates. Then we strictly define the plane principal stresses and slow-axis angle, and we give the correct expressions. Utilizing this model, we simulate a transmissivity variable plate,
