Effect of grain size on the transmission of zinc sulphide windows in the 8-12 #mu#m range of infrared

摘要

Zinc Sulphide is widely used in the fabrication of windows/domes transmitting in the far IR range (8-12 #mu#m). Fabrication of zinc sulphide windows from ZnS powder prepared by a modified acid process has been described. IR transmission of these windows in 8-12 #mu#m region has been found to be strongly dependent upon grain size of the windows.
