Abstract
An economic device based on LEDs (LED based spectrometer) is explained in this work. Instead of the wide spectrum light source and filters (commercial spectrophotometer), The LED based spectrophotometer is calibrated with standard solutions, and its measurement results is compared with the Mindray BS-200 Chemistry Analyzer (commercial spectrophotometer). The comparison shows acceptable results between both spectrophotometers with maximum error 2.33%. The errors can be reduced by applying more fining alignment. Other benefit of the new designee is to minimize testing costs.
This thesis is organized as follows:
Chapter 1: Represent an introduction of the thesis.
Chapter 2: Represent an introduction of absorption spectroscopy.
Chapter 3: Represent an introduction of LEDs and photodetectors and its applications.
Chapter 4: a complete review of the basic component of the conventional spectrophotometer and the various instrument configurations available are described.
Chapter 5: a detailed description of the design and implementation of the new spectrophotometer based on using LEDS as monochromatic light sources is introduced and a detailed description of the Testing and calibration of the new spectrophotometer is also introduced.
Chapter 6: Conclusion and future work are presented.
