Abstract
Single crystals of (NH ) Ni(SO ) .6H O represent an excellent material for filtering UV light and in an enclosed system will not deteriorate at temperatures as high as 125° C. They are particularly useful in solar-blind optical systems and sensing devices, which seek to identify the presence of UV light sources in the UV missile warning band.
