ABSTRACT:
An optical connection between optical fibers and an optical window exhibits improved long-term stability and improved measuring accuracy due to substantial transmission constancy. The surface of the optical window is coated with a thin, absorption-free coating of very hard material, thereby substantially improving the scratch resistance. The thickness of the protective coating is sized so that interfering reflection losses caused by differences in refraction indices may be avoided. The hardness of the protective coating is greater than that of the material of the optical window and its optical thickness is small in relation to the operating wavelength. The coating may be applied using ion-based, ion-beam dispersion, or microplasma methods.
