Basics of Spectral Measurement

Abstract

Modern spectroscopic measurement equipment becomes smaller and more cost effective. Therefore, it is used in more and more new application fields besides the classical one in analytics. Spectroscopic methods are applied in research and production for color measurement, chemical analysis and quality control, pharmaceutical testing, medical check up, plant growth observation, testing of light emitting devices, food control, pollution measurement, etc. Currently, they are increasingly used in process control, e.g. in dye works, chemical plants, semiconductor industry and electro plating processes.
