There are two unwanted effects, which need to be avoided or mitigated. One is the settling of iodine gas in the structure of the coating, which reduces the trasmittance of the cell windows, the other is the thermally induced spectral shift, which limits the effect of the antireflective coating. We investigate the thermal resistence of TiO2 and Ta2O5 based coatings produced by electron beam evaporation (e-beam) and plasma ion assisted deposition (PIAD). We prepared sets of quartz samples which were subject to a range of temperatures and the presence of iodine gas. We show that the choice of the coating technique and annealing procedure can mitigate the aforementioned effects.
