A practical and inexpensive design for measuring the radiation patterns and luminescent spectra of optoelectronic devices

Design and implementation of an inexpensive system capable of swift mapping of the radiation patterns and luminescent spectra of optoelectronic device s are presented. The spectrometer is programmed and monitored by a personal computer. Detailed design diagrams of the mechanical structure and electro nic hardware of the instrument are described. Measurements of some selectiv e light emitting diode and laser diode optoelectronic components are presen ted and the experimental analysis demonstrated the intended functions of th e system.
