Fiber optics coupled Xenon light sources / Light sources

Xenon light sources are useful for absorbance, fluorescence or reflectance measurements. They offer very high intensity in the UV. Standard and high-power output models are available with broadband output from UV through NIR

Fiber optics coupled Xenon light sources summary

Pulsed xenon sources are ideal for measurements where high intensity UV light can damage the sample because they are high intensity with a lower duty cycle. They offer excellent pulse-to-pulse stability during long measurements.

The 35 W xenon sources are ideal for reflectance or fluorescence spectroscopy where often a strong source is required.

High power continuous xenon sources have nominal bulb of 75 W. They provide output intensity that are almost 4x higher across the entire range compared to the 35 W xenon sources. These models have an integrated shutter that can be controlled by a TTL signal or a switch on the front panel. It allows the limitation of the exposure of the sample to this high intensity source.
