ABSTRACT:
A spectrophotometer obtains transmitted, reflected, or radiated light from at least two measuring points on at least one object and a spectroscopic light disperser disperses the obtained light spectroscopically to measuring cells for electrically indicating the spectrum of the obtained light, whereby the spectrum may be analyzed for indicating optical properties of the object at the measuring point from which the light was obtained. At least one fibre-glass cable respectively carries the light obtained at each measuring point to the spectroscopic light disperser. The ends of the fibres of each cable at the spectroscopic light dispersion are arranged in a row and the row of fibre ends of each cable are parallel to each other in a matrix of fibre ends. At least one light stop allows light from only one fibre-glass cable at a time to carry the light to the spectroscopic light disperser.
