Abstract : With the increasing use of photocathodes in all fields of basic and applied research there has arisen the need for the ability to make a quick selection of the correct photocathode for a particular situation. In a vast majority of the cases, however, it is not the photocathode alone which must be considered but a combination of photocathode and filter to be used in connection with a certain illuminating source so that a desired spectral sensitivity is achieved. These curves and tables are intended to make possible a quick selection of the proper combination. Data used in these calculations was taken from standard tables (Kodak Wratten Filters for Scientific and Technical Use and ITT Typical Absolute Spectral Response Characteristics of Photoemissive Devices), so that, although the spectral response and/or transmission of a particular combination may be slightly different because of production variations, aging, etc., these results are sufficiently accurate for most practical work.
