Report on the Chemical Treatment of Silver Chloride Sheets to Produce Filters Transmitting the Far Infra-Red
Abstract
Filters for transmitting the far infrared have been made by chemically treating rolled sheets of silver chloride to produce black powder films of silver sulphide or hard smooth films of silver sulphide. The optical properties of the filter have been measured, and it was found that suitable opacity at 1 or 2 u can be produced while high transmission at 9 to 12 u is maintained. The silver sulphide filters were found not to afford complete protection of the silver chloride from sunlight, but to afford sufficient protection to make them useful in many cases. Other films, chemically produced, are described. Only the silver sulphide films appear useful.
