Researchers at the University of South Florida have developed a compact spectrometer that is ideal for spectral measurements of non-uniform light fields.
Spectrometers are well-known in the art of analytical instruments. They have been used as detector sys-tems, concentration measurement systems and com-binations of both. Sophisticated and highly -sensitive instruments have become common place, especially in laboratory environments. However, the desire to perform more field analyses has led to portable units being developed. A common drawback of the portable unit is that, in part because of their size, they are typi-cally not suitable for the high-caliber studies that lab-versions are capable of performing. Therefore, there is a need for high-quality and reliable portable systems.
USF inventors have developed a spectrometer that is easily adapted for analysis of materials over a wide range of wavelengths, regardless of the intensity of the strength of the light fields. By using a rotating fil-ter wheel mechanism, it is possible to electronically or optically vary the sensitivity and exposure of the in-strument according to the intensity of the measured light field.
