Silicon Lenses

Optical clarity is crucial for IR applications in diverse fields such as biomedical imaging, commercial optics and unmanned systems such as those used for environmental monitoring or reconnaissance.

Cutting-edge applications such as medical optics, night vision cameras or optical systems in unmanned equipment require high-precision lenses that transmit light rays efficiently while maintaining the purity and accuracy of light. 

The following key properties of silicon lenses make them suitable for high-precision applications:

• Silicon has a relatively high refractive index, enabling precise control over the path of light rays that pass through silicon lenses. It also ensures accurate focusing and collimation of light.
• Silicon has a low dispersion rate, refracting different wavelengths of light at similar angles. This minimizes chromatic aberrations caused by the varying refraction of different colors.
• Silicon has a low absorption rate, ensuring that silicon lenses absorb very little of the light that passes through them. They transmit light accurately without significant loss, resulting in high transmission efficiency and minimal energy loss.
• Silicon lenses can be polished to a high degree, removing surface irregularities that may deflect light. A smooth surface finish, reducing light scattering, contributes to the high optical clarity of silicon lenses. 

Silicon lenses function optimally across a wide range of wavelengths. This broad spectral range enables silicon lenses to transmit light efficiently across various wavelengths.
