We have designed a software program to control and transfer data from a monochrometer into a computer. Light dispersion signals from grating were recorded and converted into electric signals by means of a phototransistor. The Keithley Multimeter 2000 then converted analog signals from the phototransistor into digital ones, which were sent to the computer via the RS-232 interface. The whole process of controlling, acquiring and storing data could be automatically conducted by the software program developed on the background of the programming language Delphi. The results of the survey on the spectra emitted from some commmercial LEDs with the use of the automated monochrometer show that the developed software program can be applied in specialized optical measurement systems using light dispersion equipment.
