Silicon (Si) is usually used in the 1.2 - 7um middle wave infrared optical window and the optical filter substrate, with peak transmission at 3 - 5um. The material has good thermal conductivity and Low density which is ideal for use in weight-sensitive applications.
We provide silicon window with high quality scratch/dig, well controlled surface flatness.
