Abstract

Photodiode array based spectrometers are increasingly being used in a wide variety of applications. However, the signal measured by this type of instrument is generally not always what the user anticipates and is often subject to contamination from stray light. This paper describes a powerful method that can be applied to stray light correction based on a relatively simple system using a monochromator-based source. The paper 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 using different interpolation methods have also been studied and are presented.
