Abstract:
A measuring device for emitted, remitted, or transmitted light from a measuring object, comprising:an optical detector for capturing light to be measured, said light being from the measuring object; a spectrometer optically connected with the detector for splitting up 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; a digital computer for controlling the photo-electric converter and the analog/digital converter; a bi-directional interface for connecting the computer with an external computer and for providing a power supply to all electrical components of the measuring device, said bidirectional interface being a high capacity data interface; a power supply circuit connected to the interface for generating the necessary supply voltage for the individual electrical components of the measuring device from the supply voltage being supplied by the external computer via the interface; and a program for controlling the computer, said program communicating between the computer and the external computer via the interface, wherein the external computer starts measuring processes and transfers the generated digital measurement data to the external computer via the interface.
