LED Pulse Selection Guide for Advanced Diagnostics: Insights from IEEE SSD 2026

Switching instead of filtering – Vincent Haude, Alexander Rolapp, and Michael Meister are presenting “Very steep LED light pulses: a selection-guideline” at the IEEE International Multi-Conference on Systems, Signals and Devices (SSD 2026): https://ssd-multiconf.org.

For many applications, such as #invitro #diagnostics, filters can be eliminated by measuring time-resolved signals. Take #fluorescence, for example. To measure it, excite fluorophores using off-the-shelf LEDs, switch off the excitation light, then measure the resulting fluorescence, and repeat. For such setups, fast optical switching times are required from the LEDs.

The authors offer a practical guide to choose the right LED for any application. By examining several parameters like those involved in LED packages, wavelength or power, they explain how to find possible limitations and chart a path to optimise a #measurement system.
