Modeling for Design and Evaluation of Optical Instrumentation
Spectral Sciences has developed a variety of passive and active optical instruments for measurement of species concentrations in the environment and in industrial process streams. Our spectral models have played key roles in the development of diode-laser, gas-correlation, laser-Raman, and UV/visible-absorption sensors through:
- Selection of optimum spectral features and path lengths
- Analysis of the effects of potential interfering species
- Prediction of absolute signal levels, and
- Development of customized spectral databases.
