Fourier Transform Infrared Spectrometer (FTIR)

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.

Application of Surface Enhanced Raman Spectroscopy (SERS) to sensing

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.

Understanding spectrometer signal-to-noise ratio

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.

General image sensors and spectrometers

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.
