Edinburgh EPLED Series

These picosecond pulsed LEDs are ideal excitation sources for a wide range of spectroscopy applications as well as being stand-alone modules.

Features:

• Sub-nanosecond pulsed LED light source
• Optimised for TCSPC
• Pre-set Repetition Frequencies from 20 KHz to 20 MHz
• External Trigger Facility
• Optimised Collimated Beam
• Spectrally Purified Output
• Built-In Drive Electronics

Pulsed light emitting diodes of the EPLED series produce sub-nanosecond (typically <750ps) optical pulses at repetition rates up to 20MHz and are therefore ideally suited to Time-Correlated Single Photon Counting (TCSPC) measurements. In TCSPC , they bridge the gap between the nanosecond flashlamp and the expensive mode-locked titanium sapphire femtosecond lasers. EPLEDs are fitted with bandpass filters for spectral purity and are available with emission covering the UV-Visible spectrum, starting from 250nm.

Other picosecond pulsed light emitting diodes may also be used. Please enquire for integration options that are available.
