  • Publication number: 20210249223
    Abstract: Substrates that can act as optical elements for transmitting infrared light and that have low reflectance for infrared light and the assembly of such substrates with a source of infrared light and/or with an infrared-sensitive optical component. The substrates are suitable for cover glasses and optical elements, such as lenses, prisms, or mirrors to be used with infrared light. Ions are implanted into a substrate in order to reduce its reflectance of infrared light.
