Assembly of a fast multi resolution spectromether system for simultaneous measurement of absorption and luminescence spectra

Yousef Y. A.

Optica Applicata

2005

Vol. 35, nr 1

67-76

In this work, the design and assembly of a dual spectrophotometer system capable of measuring the absorption as well as time resolved luminescence of liquid, gaseous, or solid samples are reported. The system incorporates a 1024x376 elements coupled charge detector (CCD) capable of monitoring changes in optical spectra with time delays as short as few microseconds time scale. Such a design reduced significantly the costs os purchasing two separate systems containing similar optical and electronic components. In addition, the design enabled further investigations on the photodegradation mechanism for a benzimidazole based pesticide.
