Abstract : The article describes a method which removes the difficulties hitherto encountered in measuring the transmission of glass fibers, when laborious and lengthy grinding and polishing of the fiber front and protection against damage were necessary. In the new method the upper end of the fiber is cemented with Canada balsam on a ground glass plate, the lower end being dipped in a drop of immersion liquid in the entrance window of the multiplier. The light travels through the fiber from the source at the upper end of the fiber and the transmission is characterized by the multiplier current intensity as a function of the fiber length.
