The performance of F-containing optical materials can degrade rapidly in the extreme ultraviolet (EUV), VUV, deep ultraviolet (DUV) and / or UV spectral ranges as a result of radiation degradation, leading to reduced optical performance and lifetime of optical applications and / or systems.SOLUTION: The optical system comprises a bulk material comprising an optical material comprising fluorine (F). When a bulk material is under extreme ultraviolet (EUV), vacuum ultraviolet (VUV), deep ultraviolet (DUV) and / or UV radiation, the bulk material is exposed to an environment with a pressure ranging from atmospheric pressure to vacuum. The environment includes at least one type of gas or vapor. At least one type of gas or vapor comprises polar molecules.SELECTED DRAWING: Figure 1

This invention discloses a method for constructing and modeling degradation of multi-source data for cross-medium imaging under complex sea conditions, belonging to the field of underwater optical imaging. Addressing the difficulty of existing technologies in uniformly describing geometric distortion caused by sea surface fluctuations and radiation degradation resulting from water absorption and scattering, this invention integrates multi-source data from real-sea observations, controlled laboratory tests, and auxiliary references. It constructs a wave interface function and establishes a refractive distortion displacement field based on Snell's law, while simultaneously building a water radiation degradation model to form a unified degradation expression. Furthermore, it expands the sample space through physically guided data enhancement, generating a dataset with multi-dimensional degradation labels. This invention achieves joint modeling of geometric and radiation degradation in cross-medium imaging, providing a high-fidelity, high-generalization data foundation for image restoration model training.
