Sapphire optical windows are flat polished products based on single crystal sapphire. Depending on the use environment, they sometimes need to be provided with various optical coatings such as anti-reflection film, high-reflection film, spectroscopic film, metal film, etc. to adapt to the transmission (cut-off) or reflection requirements of different spectral bands.
