Silicon Lenses
Silicon lenses are optical devices made from high-purity single-crystal quartz material, featuring an extremely high refractive index and excellent light transmission properties. Silicon lenses exhibit high transmittance in the visible and near-infrared spectral ranges, and have a very low absorption coefficient in the ultraviolet spectral range. Therefore, they offer excellent light transmission performance across various wavelength ranges.
