VD0775 Calcium Fluoride (CaF2) Evaporation Materials

Calciumfluoride Evaporation Materials Description

Calciumfluoride (CaF2)-A evaporation materials are frequently used in thin film deposition processes for optical coatings and semiconductor applications. CaF2 displays high transparency in the ultraviolet, visible and infrared ranges, thereby making it suitable for various optical components such as lenses, windows and prisms.

The material exhibits a cubic crystal structure and has a high melting point of approximately 1 414 °C, which ensures stability during the deposition process. The low vapour pressure facilitates controlled evaporation, thereby ensuring uniform film deposition.

CaF2 evaporation materials are known for their high purity and stoichiometric composition. This results in films meeting defined optical parameters with minimal defects, thereby rendering them suitable for applications that require precise optical properties, for example in photolithography, optical coatings for laser systems and infrared spectroscopy.

Furthermore, calcium fluoride is chemically inert and exhibits good thermal stability, which makes it compatible with various substrate materials and deposition conditions. Its large band gap and low refractive index contribute to minimising optical losses in thin film applications.
