The challenges of developing large-scale 316L(N)-IG mirrors for the collection system of the ITER divertor Thomson scattering (DTS) diagnostic are under consideration. These are second mirrors (M2), located out of direct plasma sight, require an optically smooth surface to ensure efficient light collection. Two approaches to surface finishing abrasive and magnetorheological polishing were investigated. On small-scale samples (22 mm and 6x 6 mm), the target roughness (R_q/λ <0.012) was achieved, while scaling to larger substrates revealed degradation of surface quality, indicating the need for further process optimization. The results confirm the applicability of the developed polishing techniques and provide a basis for a scalable preparation route for ITER optical components. Keywords: abrasive polishing, magnetorheological polishing, steel 316L(N)-IG, ITER, second mirrors.
