Silicon IR blanks are high-purity silicon substrates crucial for infrared optical applications. They are predominantly used to manufacture lenses, mirrors, and windows that operate in the infrared spectrum. Silicon’s high thermal conductivity and low absorption rates at IR wavelengths make it ideal for components in thermal imaging and telecommunications systems.
