Silicon (Si) optical window
PRODUCT CATEGORIES
Silicon material has good thermal conductivity, low density and high hardness, ranging from 1 to 7μm has good light transmittance. Monocrystalline silicon is usually used for 3-5μm medium wave infrared optical window and optical filter substrate are also common materials for laser mirror substrate.
