Abstract
The problems involved in the development of ultraviolet transmission filters are discussed and criteria of stability, efficiency, and ease of preparation are applied to the materials suggested by previous workers. By the selection of the most suitable previous filters and the introduction of several new filters, a set of band pass filters for the 2400–3800A region of the ultraviolet is developed. These have a half-width of 200A and a maximum transmission of 30 percent, on the average. Quantitative spectrophotometric data are given for all components and filter combinations used. Suggestions are made for the further development of these tools.Keywords
