Articles
Method notes, application notes and primers written by the Evolve Sensing engineering team. Each article explains the measurement, the specifications that determine the result, and the cases where a technique or instrument is not the right choice.
Primer
Replacing a spectrometer without rewriting the instrument
An engineering guide to migrating from an end-of-life or constrained spectrometer, covering what to map before ordering a prototype, where a replacement can improve the architecture, and how to keep the transition predictable.
Diagram
Spectral balance in broadband measurements
How intensity roll-off across a broadband source limits a single-bench measurement, and how a dual spectrometer system addresses it.
Product story
Through-container Raman on powders, blends and turbid liquids
Through-container measurement on powders, blends and turbid liquids, and how an interferometric architecture changes what is practical.
Primer
Spectrometer requirements for optical coherence tomography
Line rate, roll-off and sensitivity, the three specifications that determine whether an OCT system produces a usable image.
Method note
CMOS and CCD detectors compared
Read noise, dynamic range, readout speed, and the three cases where the expected choice turns out to be the wrong one.
Method note
Thermal stability in miniature spectrometers
How wavelength drift with temperature affects calibration, why the drift specification matters, and how to verify a stability claim in your own setup.
Application note
LIBS in industrial environments
Laser-induced breakdown spectroscopy on coal, ore and slag, including what the technique requires from a spectrometer and what it requires from the rest of the installation.
