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