Spectra Feature: Electrochemical Response

Posted on: September 26th, 2019

Background This spectra feature was provided by Pine Instruments as an example of a spectroelectrochemistry application that measures electrochemical response over a range of applied electrical potential and correlated against energy absorption by wavelength. Researchers Greenlee, et al. were measuring the electrochemical response of PMDI’s that were functionalized with 4-(dimethylamino) pyridinium (DMAP+) groups.  The functionalization…

Spectroelectrochemistry Applications and Instrumentation

Posted on: September 26th, 2019

Electrochemistry is an extremely valuable tool for examining the kinetics of a wide range of oxidation-reduction reactions.  In these types of reactions, electrons are exchanged between atoms spontaneously,  which forms the basic physical principle behind chemical batteries.  Just as specific oxidation-reduction reactions can cause electron flow, i.e. current, the same process can also work in…

Spectra Feature: Single and Multi-Mode VCSEL Testing

Posted on: September 12th, 2019

This Month’s spectra were contributed by a current Avantes customer in the manufacturing of Vertical Cavity Surface Emitting Lasers (VCSEL). Parameters Measured We utilize Avantes spectrometers to measure spectral peak wavelength, centroid, SMSR, FWHM, and RMS spectral bandwidth of a broad range of VCSEL-based laser products. Wavelength Range 650nm to ~1000nm Laser Power 10’s of…

Spectroscopy Applications in the Development of VCSEL Technology

Posted on: September 12th, 2019

Vertical Cavity Surface Emitting Lasers (VCSELs) are instrumental in many recent technological advancements, with several advantages over Light Emitting Diodes (LEDs) and Edge Emitting Lasers (EELs). Manufacturers of these devices, as well as device integrators, require optical spectrometers featuring high resolution, high-speed triggering response, and short integration time specifications to test VCSELs. Avantes is the…

Laser-Induced Breakdown Spectroscopy in the Physical Sciences

Posted on: August 20th, 2019

Laser-Induced Breakdown Spectroscopy employs a laser to ablate the surface of a sample which creates a small plume of plasma. Using a form of atomic emission spectroscopy, the light of this plasma is captured and analyzed for quantitative and qualitative atomic properties. As the popularity of this method of analysis grows and researchers find new…
