Silicon infrared spheric optical lenses are made from high-purity silicon, known for its strong infrared transmission properties. These lenses are particularly effective in near-infrared to mid-infrared applications, including telecommunications and security systems. Silicon lenses are favored for their durability, thermal stability, and ability to provide clear, focused imaging across various IR wavelengths.
