Stray light correction for diode-array-based spectrometers using a monochromator

Salim, S. G. R., Fox, N. P., Hartree, W. S. , Woolliams, E. R., Sun, T. & Grattan, K. T. V. (2011). Stray light correction for diode-array-based spectrometers using a monochromator. Applied Optics, 50(26), pp. 5130-5138. doi: 10.1364/ao.50.005130


Photodiode-array-based spectrometers are increasingly being used in a wide variety of applications. However, the signal measured by this type of instrument often is not what is anticipated by the user and is often subject to contamination from stray light. This paper describes an efficient and low-cost stray light correction approach based on a relatively simple system using a monochromator-based source. The paper further discusses the limitations of using a monochromator instead of a laser, as used by previous researchers, and its impact on the quality of the stray light correction. The reliability and robustness of the stray light correction matrix generated have been studied and are also reported.
