Si(Silicon)
Silicon offers high thermal conductivity and low density, making it suitable for laser mirrors. However, since silicon has a strong absorption band at 9 µm, it is not suitable for use with CO2 laser transmission applications. Silicon optics are also particularly well suited for imaging, biomedical applications. Our Quantum Cascade Lasers offer a number of output wavelengths for use with silicon optics. Silicon has a transmission range from 1.2 µm to 8.0 µm. Silicon has a refractive index of 3.423 at 4.58 µm.
