Silicon lens

silicon lenses perform well over a broad spectral range from near-infrared to long-wave infrared. They have a relatively high refractive index, allowing for precise control of the path of light passing through the silicon lens and ensuring accurate focusing and collimation of light. Silicon has low dispersion, refracting light of different wavelengths at similar angles, thus minimizing chromatic aberration. The low absorption rate of silicon ensures that silicon lenses absorb very little light, resulting in high transmittance efficiency and minimal energy loss. Silicon lenses can be highly polished to reduce the deflection of light by surface irregularities, thereby improving optical clarity.
