Abstract
A photomultiplier tube assembly for use in high speed light testing apparatus for making a series of light measurements in rapid succession. Electronic circuitry is described for removing noise from a light measurement signal generated by the photomultiplier tube. Other circuitry is described for sensing the presence or absence of a measured object in a testing apparatus and for switching the photomultiplier tube on and off in response thereto. Circuitry for generating a signal to reject defective articles subsequent to testing is described.
