MGF2 OPTICAL THIN FILM INCLUDING AMORPHOUS SILICON OXIDE BINDER, OPTICAL ELEMENT PROVIDED WITH THE SAME, AND METHOD FOR PRODUCING MGF2 OPTICAL THIN FILM |
摘要 |
An MgF2 optical thin film is formed on an optical surface of a base material. The MgF2 optical thin film includes MgF2 particles and an amorphous silicon oxide-based binder which exists on the surfaces of the MgF2 particles and between the MgF2 particles. Owing to this amorphous silicon oxide-based binder, the optical thin film can have high mechanical strength and high adhesion to the base material, while having excellent environment resistance and a lower refractive index.
