Single Crystal Silicon
Single Crystal Silicon exhibits a transmission range of 1.2 to 8 microns (uncoated). However, it demonstrates a strong absorption band at 9 microns, making it particularly suitable for applications within the 3-5 micron range. Beyond this, floating zone silicon can be utilized. This material offers numerous advantages, including its affordability, making it an excellent choice for weight-sensitive applications. Furthermore, monocrystalline silicon possesses a lower density, greater hardness, and improved durability compared to germanium, rendering it less prone to brittleness. Consequently, it finds extensive application in various industries such as the military, imaging, scientific research, as well as optical coating substrates.
Detail & Parts
Advantages of Silicon windows
- Silicon windows have a low density of 2.329 g/cm3, ideal for weight-sensitive applications. In addition, silicon is not as brittle as germanium and zinc selenide, and has better thermal stability.
- Since silicon has a cubic crystal structure, it does not exhibit birefringence. Birefringence degrades infrared imaging performance, so it is important to choose a non-birefringent material.
