Si lens

Product Info

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.
