Abstract

Spectrochemical procedures occasionally call for the use of a wire screen to reduce the intensity of a light source. Sometimes the screen is specified as having a given optical transmittance; more often it is described as being of a given mesh. Such screens are presumed to be used at normal incidence and when used as an attenuator are known to be optically stable with respect to time and ideally neutral with respect to wavelength (<i>1</i>).
