EPLED - sub-nanosecond pulsed LED light sources

EPLED - sub-nanosecond pulsed LED light sources from Edinburgh Instruments Ltd.

Keywords: instruments, Spectrometer, spectrophotometer

The EPLED range of sub-nanosecond pulsed LED light sources are ideal excitation sources for a wide range of spectroscopy applications as well as being stand-alone modules. Standard wavelengths are available from 250-380nm.

The EPLED picosecond pulsed LEDs are a new excitation source for fluorescence lifetime measurements. In Time Correlated Single Photon Counting (TCSPC), they bridge the gap between the nanosecond flashlamp and expensive mode locked Titanium Sapphire femtosecond lasers in the UV region.

The EPLEDs are pre-adjusted in respect to pulse width and peak power, with particular attention paid to reducing both secondary shoulder and a long tail in the temporal profile. The output of the UV-EPLED Series have a guaranteed pulse width of less than 950ps. The EPLEDs are robust, maintenance free, easy to operate and have proprietary beam conditioning optics.
