Spectroscopy / Spectrometers

Laser-induced breakdown spectroscopy (LIBS) is a fast, nondestructive analytical technique that uses a laser to generate a plasma on the surface of a sample, producing emission spectra that can be analyzed to determine the elemental composition of the material.  John Gilmore introduces the fundamental principles of LIBS and its applications in various fields, including environmental monitoring, material science, and forensic analysis.

Light can be used in many ways to understand, study, and spectroscopically characterize the components that may exist in water. Stephanie Butron and Eric Mesa of Hamamatsu Corp. discuss the various markets that benefit from such measurement, the photonic tools currently available to perform such measurement, and how users can select tools for specific applications.

John Gilmore, MEE, from Hamamatsu Corporation speaks with us on Raman technology from Hamamatsu Photonics K.K. Listen along as we chat about this evolving technique and how devices such as Hamamatsu’s Raman module have been designed to meet growing needs for compact and portable spectrometry.

This webinar will review the basic theory behind a Michaelson-Morley interferometer, and will apply it directly to today’s modern MEMS-based FTIR engines.

Surface enhanced Raman spectroscopy (SERS) is a vibrational spectroscopic technique that has risen to prominence in sensing owing to its outstanding sensitivity and selectivity. Over the past decade, in particular, SERS has enabled the identification and quantification of a wide array of analytes, including small molecule drugs and toxins, metabolites, and disease biomarkers. It has also enabled to monitor chemical reactions in situ in real time and has recently expanded substantially in the direction of pathogen detection, in which the identification of parasites, bacteria, and viruses has been demonstrated also through rapid, low-cost assays.

Learn why one of the most important parameters when selecting, and implementing a spectrometer is the signal-to-noise ratio (SNR). While the definition of SNR varies greatly within the photonics industry, this course defines a commonly used methodology and gives practical examples of the same.

There are many spectrometers on the market for various spectroscopy applications. In this presentation, you can learn what’s unique about Hamamatsu’s spectrometers. We are not just a run-of-the-mill supplier; we are uniquely positioned to provide every aspect of spectrometer technology. Hamamatsu is well-known as a quality sensor (CCD, CMOS) provider, and now also for MEMS/MOEMS solutions including transmission gratings and nano-imprinted surface-enhanced substrates (SERS) and micro-spectrometers. We combine these unique technologies to manufacture portable Raman and other optical modules. To cover the NIR, many are turning towards MEMS-FPI tunable filters, the MEMS-FTIR engine, or compact InGaAs-based thin flat spectrometers, forming low-cost handheld spectroscopy solutions.

Learn how micro-spectrometers can be used in reflection mode to identify beer type through color measurement.

This webinar discusses what trade-offs you should consider when choosing (or designing) a spectrometer to best suit your application.
