Anti-reflective coatings can significantly increase the performance of the secondary light-sensing bolometer in these experiments. As a first step toward these improvements, coatings of SiO2, HfO2, and TiO2 on Ge and Si wafers were fabricated and characterized at room temperature and multiple angles of incidence.
