ABSTRACT:
A sensor for a spectral analyzer includes a relatively movable holder and probe, where the probe is fitted with a reflector, and the holder is provided with a pair of adjacent optical fibers for transmitting/receiving light. When the probe abuts the surface of the object to be measured, the probe and holder move relatively so that the fiber pair approach the reflector. A switch activating the analyzer for data collection is operated in response to the change in reflected light intensity caused by the relative movement.
