The New Technologies Shaping Near-Infrared Spectroscopy
Near-infrared spectroscopy is the branch of vibrational spectroscopy related to the molecular absorption of light between ~750 to 2500 nm, which has a variety of industrial and medical applications. It has evolved from collecting data after the fact to gathering real-time sensor information in the field.

A Laser Points Toward Disease Diagnosis
A critical starting point in reducing the incidence of chronic disease involves detecting, locating, and accurately evaluating disease in its initial stages. One important step in tackling these challenges will be developing light-based technologies such as near-infrared (NIR) and mid-infrared (MIR) spectroscopy.

SwRI Delivers Ultraviolet Spectrograph for Jupiter Mission
An ultraviolet spectrograph (UVS) designed and built by Southwest Research Institute (SwRI) is the first scientific instrument to be delivered for integration onto the European Space Agency’s (ESA) Jupiter Icy Moon Explorer (JUICE) spacecraft. Scheduled to launch in 2022 and arrive at Jupiter in 2030, JUICE will spend at least three years making detailed observations in the Jovian system.

Filtering Visible Light According to Wavelength and Bandwidth
Some supercontinuum lasers have an output power in the range of tens of watts with a wavelength range that covers the entire UV-VIS range and a portion of the NIR region. With these performance specifications, the combination of a tunable filter and a broadband light source is more efficient than multiple discrete light sources.

Compact MEMS-FPI Sensor for Portable NIR Spectrometers
Hamamatsu’s MEMS-FPI spectrum sensors utilize a built-in MEMS Fabry-Perot interferometer and InGaAs PIN photodiode to measure NIR spectra. With their high sensitivity to NIR wavelengths and their compact size, they are suitable for portable devices used to identify materials. For example, as shown in this video, a MEMS-FPI sensor and an NIR light source were integrated into a handheld device to identify textile materials based on their NIR reflection spectra.

Ellipsometry: What Is It and What Can It Do for You?
Wed, May 13, 2020 1:00 PM - 2:00 PM EDT
Spectroscopic ellipsometry is a nondestructive technique that uses polarized light to probe a sample. In this webinar, presented by the J.A. Woollam Co., you will learn about the fundamental principles of ellipsometry, how these principles lead to highly accurate measurements of coating thickness and optical properties, and how ellipsometry measurements compare to other characterization techniques.
