Description:
Zinc Sulphur(ZnS) material have two grades and can be used in imaging systens, Regular grade material
is grown by the chemical vapor deposition process, This material is often used in the 3um to 5um and 8um
to 12um region, It has resonable hardness and is moderately priced, It is avaiable in large size as well. It can
replace ZnSe in certain harsh environment, Multi Spectral grade ZnS is treated after growth to eliminate microscopic
voides and defects which occur in the regular grade, thus extending the usefulness of this material to including the visible region.
