Si Window & Lens

Product Details of

In the range of 3-5 μ m, silicon is the most commonly used material for making optical lens and optical window in high-efficiency infrared imaging system. Silicon has the characteristics of high refractive index (about 3.4 at 3-5 μ M band), small surface curvature and color difference.
