Abstract
A measuring device for emitted, remitted or transmitted light from a measuring object is provided having an optical detector for capturing light to be measured, said light being radiated from the measuring object; a spectrometer optically connected with the detector for dispersing the measuring light into its spectral components, said measuring light being captured by the detector, said spectrometer including a photo-electric converter for generating respective analog electrical signals from the spectral components of the measuring light; an analog/digital converter for converting the generated analog electrical signals into respective digital measurement data, said analog electrical signals being generated by the photo-electric converter; a digital computer for controlling the photo-electric converter and the analog/digital converter; a bidirectional interface for connecting the computer with an external computer; and a program for controlling the computer, said program for communicating between the computer and the external computer via the interface, wherein the external computer starts measuring processes and transfers the thus generated digital measurement data to the external…
