Abstract

Traditionally, determining the spectroradiometric output of a light source has been a long, tedious, rather time consuming process. Many hours could be spent in calibrating the spectroradiometer for spectral response, collecting data on the source under investigation and in properly reducing the data. Due to rapid advances in electronic technology, it is now possible to obtain an automated spectroradiometer system at a modest cost which can be interfaced to a relatively inexpensive programable desk top calculator or microcomputer to provide a system which can automatically conduct a spectral scan and provide a real-time printout or display of spectral output under program control. This paper will cover the basic parameters to consider when selecting a spectroradiometer and also the features a spectroradiometer should have in order to be completely automated and capable of operating under programed control. In addition, requirements for measuring a wide range of light sources ranging from continuous or steady state sources from sunlight to starlight and also pulsed sources such as Xenon flash lamps and pulsed LED's will be briefly described. Finally, some of the present commercially available automated spectroradiometer systems will be described.
