Silicon (SI) plano convex lens
PRODUCT CATEGORIES
- Silicon (SI) single crystal is a chemically inert material with high hardness and insoluble in water. It has good light transmission performance in 1.2 – 7μm band and 30-300 in far infrared band μm also has good light transmission performance, which is not possessed by other infrared materials.
- Silicon (SI) single crystals are commonly used as 3 – 5μm medium wave infrared optical lens, optical window and optical filter substrate.
- Because of its good thermal conductivity and low density, the material is often used to make laser mirrors and occasions sensitive to volume and weight.
