EPLED SERIES Picosecond Pulsed UV & Vis LEDs The EPLED picosecond pulsed LEDs are ideal excitation sources for fluorescence lifetime measurements providing coverage in the UV and visible ranges. In Time-Correlated Single Photon Counting (TCSPC) they bridge the gap between the nanosecond flashlamp and expensive mode-locked Titanium sapphire femtosecond lasers. In addition, their external trigger capability makes them suitable for standalone operation in a wide range of spectroscopy applications. The EPLEDs are pre-adjusted for an optimum pulse width, with particular attention paid to reducing a long tail in the temporal profile. KEY FEATURES Optimised for TCSPC 15 pre-set repetition frequencies from 2.5 KHz to 20 MHz External trigger capability Spectrally purified output Fully integrated & compact design Extremely low RF radiation Optimised collimated beam Drive electronics included EPLEDs are robust, maintenance free, easy to operate and have proprietary beam conditioning optics.
