Hafnium Oxide (CAS: 12055-23-1) is a white powder widely recognized as one of the most frequently used high-refractive-index materials for optical coatings. Due to its high refractive index and broad low-absorption range, spanning from the near-ultraviolet (UV) to the mid-infrared (IR), hafnium oxide is an ideal choice for optical coatings. Thin layers of this material are often applied to create hard, scratch-resistant coatings, making it suitable for applications like near-UV laser systems, anti-reflective coatings, and dielectric mirrors.
