This month’s spectra celebrates the Halloween season as we measure spectra results obtained from BLOOD! Background/Applications: Absorption spectroscopy is used across a wide range of industries and is an effective form of scientific analysis in many fields of research. This includes the medical field for studying blood. For example, absorbance spectroscopy has been used to…
Read MoreBackground 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…
Read MoreThis 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…
