Xenon Flashlamp / Light Source Xenon Flashlamp

Sarspec's LS-XeF is designed to be the state-of-the-art pulsed Xenon light source, providing microsecond-duration pulses of broadband light with exceptional arc stability and life characteristics. This light source is a compact solution with a high radiant and powerful flash lamp, offering a wide range of flash energy and repetition rate in a pre-aligned module.

This light source can be synchronized with all Sarspec’s spectrometers where the flashes frequency and delay can be controlled. Combined with Sarspec’s Spectrometers, Optical Fibers and Accessories it’s a great and flexible solution for every laboratory.

The flexibility of this light source makes it a great solution for Fluorescence/Phosphorescence measurements due the high energy pulses and UV performance. Its large spectrum and stability makes it suitable also for Absorbance, Reflectance and Transmittance. Its high intensity in the UV makes it the perfect solution for Fluorescence measurements in biological samples.
