摘要：A device for use in producing a scanning beam of radiation comprises a rotormember carrying two optical wave guides arranged so as to direct light along the rotaryaxis of the rotor member, then radially outwardly to pass from one wave guide to theother, then radially inwardly and finally along the said rotary axis again.
When the device is adapted for investigating liquid samples, a turntable, carrying anumber of vials containing liquid samples at spaced locations around its periphery, isrotated in indexing fashion and, during each dwell period of the turntable, the rotormember is rotated so that the circularly scanning beam of light leaving the firstmentioned wave guide scans each of the vials in turn at least once.
