Product Code SIFZP12-1 IR Polished Silicon (Si) optical window 12mm Ø x 1mm FZ, Float-Zone Grade (no absorption band at 9μm) ...
Silicon FZ - Circular Windows
Circular Silicon Float Zone Windows from Stock.
Optical grade Silicon is normally specified with a resistivity of 5 to 40 ohm-cm which is higher than most semiconductor applications. The windows listed here are made from FZ, Float Zone material which does not have this Si-O absorption at arount 9 microns wavelength.
Very high resistivity material can be supplied on special order, particularly for TeraHertz applications.
