Broad IR Transmission: Silicon lenses are effective in both MWIR and LWIR ranges, making them versatile for various IR applications.

Low Density: Silicon has a low density (2.33 g/cm³), approximately half that of Germanium (Ge) or Zinc Selenide (ZnSe), making it ideal for weight-sensitive applications.

Hardness and Durability: Silicon is harder and less brittle than Germanium, offering better durability and resistance to mechanical stresses.

Chemical Resistance: Silicon exhibits high chemical resistance, ensuring longevity and stability in harsh environments.

Cost-Effective: Silicon is relatively inexpensive compared to other IR materials, providing a cost-effective solution for IR optics.

Applications: IR optics, thermal imaging, laser systems, military optics, medical equipment.
