Substrates


These sapphire windows contain no impurities and provide high transmission without any absorption, covering the visible and infrared regions of the spectrum.
Silicon is a monocrystal mainly used in semiconductors and does not absorb in the IR range from 1.2 µm to 6 µm.
Germanium as a monocrystal, which is mainly used in semiconductors, is non-absorbing in IR ranges from 2 µm to 20 µm.
