ABSTRACT:
A versatile optical analysis system comprising a spectrophotometer having a collimated radiation source, an output port for the radiation, an input port for external radiation, a detector, and means for processing electrical signals representative of radiation from a sample to be analyzed. The system also comprises one or more remote terminals where the sample is located, and novel radiation piping means for selectively piping radiation from the spectrophotometer to the remote terminal or vice versa. Novel remote terminals are also described for carrying out diffuse reflection, external reflection, or emission analysis.
