The incorporation of large amounts of aluminum substantially alters the ir characteristics of BaF 2 /ThF 4 ‐based glasses. In particular, a distinct peak associated with aluminum is observed in the fundamental reflectivity spectrum at ∼ 625 cm −1 , with a concomitant shift of the ir absorption edge to higher frequencies. Although beneficial for glass formation, the addition of aluminurn has a deleterious effect on the ir transparency range of heavy‐metal, fluoride glasses.
