Aurora LIBS Spectrometer
Not all LIBS spectrometers are created equal. The Aurora LIBS Spectrometer—designed by the LIBS experts at Applied Spectra—delivers the high spectral resolution and precise gate timing control required for effective LIBS analysis.
Aurora’s flexible number of spectrometer channels makes it an ideal detector for broadband as well as narrower band analysis focusing on a few specific elements. And Aurora features integrated data analytics, including our TruLIBS™ emission database and LIBS GDT (Graphical Development Tool) chemometric software; together, these enable our customers to rapidly identify complex emission peaks and process LIBS spectra for accurate quantitative and material forensic analysis.
Not Just a Component—A Complete LIBS Spectrometer Solution
The LIBS experts at Applied Spectra have a long and successful history delivering LIBS instrument solutions to researchers and industrial customers. We applied this expertise and experience to Aurora’s hardware design and software features. Aurora strikes the right balance between spectral resolution and detection sensitivity—from UV to NIR spectral ranges. Don’t waste time wondering if you have the right spectrometer configuration. Aurora lets you focus attention on your applications or research.
Integrated Analytics Module to Simplify Data Analysis
The Aurora LIBS Spectrometer inherits powerful, integrated data analytics tools from our industry-leading RT100 Series LIBS instruments. Aurora uses TruLIBS™, Applied Spectra’s proprietary emission database, obtained from real LIBS plasmas, to quickly and accurately identify complex LIBS emission peaks. Aurora includes other essential spectral analysis software features, such as continuum background subtraction, peak area integration, and curve-fitting of overlapping spectra, which allow users to efficiently process LIBS peaks and obtain quantitative answers. With Aurora, you can monitor LIBS intensity statistics during multiple laser pulse sampling—an important technique for optimizing laser sampling protocols during bulk chemical analysis.
Forensic Analysis Capability
As a standard software feature, Aurora offers Applied Spectra’s LIBS GDT (Graphical Development Tool) chemometric software, developed in partnership with NewFolder Consulting. LIBS GDT discriminates complex substances based on PCA/PLS-DA and other algorithms. With LIBS GDT, Aurora customers can test and identify useful spectral features for sample discrimination and then store them in the data library as characteristic spectra of the sample. Any LIBS spectra of questioned substances can later be tested against the library to yield a highly effective sample ID.
Flexible Number of Spectrometer Channels
For the standard 6-channel configuration, Aurora extends the spectral coverage from UV to NIR (190 to 1040 nm) while maintaining the resolution better than <0.1 nm for the most of UV to VIS range. Aurora can be customized with fewer spectrometer channels to focus on narrower spectral ranges and specific elements. Whether you’re looking to perform forensic analysis or quantitative analysis of certain elements, the spectrometer channel number can be customized to deliver a cost-effective solution.
Randomized Fiber-Optics Bundle for Efficient Light Collection and Throughput
Aurora features a specially-designed randomized fiber-optic bundle for maximum light throughput to all spectrometer channels. Collected light can be efficiently coupled into the fiber-optic bundle and evenly distributed into all spectrometer channels, ensuring balanced detector response for UV to NIR wavelength ranges.
