AI Technical Summary
Existing optical components with multilayer films suffer from inadequate hardness and abrasion resistance, particularly when exposed to external environments, leading to potential deterioration of optical properties due to surface scratches.
The development of an optical component featuring a multilayer film composed of fluoride films containing rare earth or alkaline earth metal elements, with a controlled band gap ratio determined by backscattered electron energy loss spectroscopy, and formed through a sputtering process that includes fluorination of cationic element films to enhance durability.
The resulting optical component exhibits enhanced hardness and wear resistance, maintaining optical properties even under external exposure, with improved durability and resistance to surface scratching.
