We present a review of recent analysis of optical specifications for the Laser Mégajoule (LMJ) plain size (40 cm × 40 cm) components. Our studies are mainly achieved using the Miró laser propagation code. The purpose of this paper is first to describe the different methods used to model the wavefronts transmitted by the components. Then, we give examples of evaluation results for the following issues: surface imperfection specification on the 1ω phase plate, surface conditioning defects tolerance on 1ω transport mirrors, Power Spectral Distribution (PSD) specifications of the transmitted wavefront and of the roughness on the components of the amplifying section.
