Pulsed light sources

We make and supply a range of picosecond pulsed semiconductor light sources. Our range includes the EPL and EPLED Series of products that are designed for use at different wavelengths and are compact fully integrated systems optimised for Time Correlated Single Photon Counting (TCSPC).

One key advantage is that there is no requirement to purchase a separate driver making the EPL and EPLEDs easier to share between colleagues.

Applications for the picosecond pulsed diode lasers include fluorescence lifetime measurements that use time correlated single photon counting as the measurement technique. Typical instrumentation that require these sources are fluorescence lifetime spectrometers and fluorescence lifetime multiwell plate readers for spectroscopy applications in biochemistry, biology, photophysics, semiconductor physics, bio-chemical assays etc. Customised versions of the diode lasers can be also supplied for integration within various types of analytical instrumentation.

EPL Series*

The EPL picosecond pulsed diode lasers are a new excitation source for fluorescence lifetime measurements that bridge the gap between the nanosecond flashlamp and expensive mode locked Titanium Sapphire femtosecond lasers.

The EPL lasers are pre-adjusted for an optimum pulse width, with particular attention paid to reducing a secondary shoulder. The output has a guaranteed pulse width of less than 100picoseconds.**

The EPL lasers are robust, maintenance free, easy to operate and have proprietary beam conditioning optics.

EPLED Series

EPLED

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.
