The SpectraLaser Elemental Analyser prototype is a Laser-Induced Breakdown Spectroscopy (LIBS) system designed for
analyzing non-organic samples. Developed by a team of undergraduate students, the project aims to create a cost-effective
alternative to current LIBS systems for applications in hazardous environments, extraterrestrial exploration, and
educational institutions.
Key project goals include consistently generating plasma, achieving less than 10% variance in measurement results over
five samples, and identifying known alloys or objects within 90% accuracy of expected spectral emission. The system is
digitally controlled, converting analog spectrometer data into digital form and outputting results in under a minute.
Optically, the system utilizes an Nd:YAG laser to generate plasma, with light emission analyzed through a Czerny-Turner
spectrometer. An IR sensor detects plasma bloom triggering the capture of spectral data by a CCD, which is then
processed and displayed or transmitted.
Compared to existing LIBS systems, this prototype offers lower cost, digital control, and faster results. Its design
emphasizes safety, cost-effectiveness, and adherence to relevant standards. The system’s potential applications range from
school demonstrations to extraterrestrial exploration, addressing the need for rapid, on-site sample analysis while reducing
costs and increasing efficiency, particularly in educational institutions and space exploration missions.
