Si Optical Silicon Lenses 0.1mm Tolerance Germanium Windows
Optical usage infrared Si Silicon windows
1.Feature of Silicon window:
Silicon windows have good transmission in the range from 1.2 to 7.0 µm, with little or no distortion of the transmitted signal. Silicon has an advantage over other IR materials due to its low density (about half that of Zinc Selenide or Germanium), making it ideal for optical systems where weight is a significant factor. Silicon windows are also more robust and less brittle than Germanium windows, and have high thermal conductivity
2. Application:
- Ideally suited for weight sensitive applications having a Density of 2.329 g/cm3
- Typically used in the 3 - 5μm for Thermal Imaging Systems
