1.1/2" and 1" Diameters Available
2.Uncoated Window for Visible and IR Applications in the 600 nm - 16 µm Spectral Range
Wuhan Especial Optics' Precision Zinc Selenide (ZnSe) Windows are offered in Ø1/2" and Ø1" sizes. They are available uncoated or with an AR coating on both sides that provides <1% average reflectance from either 1.65 to 3.0 µm or 7 to 12 µm (see the Graphs tab for transmission and reflectance plots). Due to its wide transmission band, along with its low absorption in the red portion of the visible spectrum, zinc selenide is ideal for optical systems that combine a 10.6 µm CO2 laser with a 633 nm HeNe alignment laser.
