Pulsed Xenon Light Sources

Excelitas PAX Light Sources are compact, integrated, precision-aligned Xenon light source solutions containing a flash lamp, trigger circuit, and power supply in an EMI-suppressant enclosure.

The PAX family is the ideal choice for clinical diagnostic, in-vitro diagnostics, life sciences, drug discovery, proteomics, and analytical instrumentation applications. These miniaturised modules can offer significant advantages over LEDs in analytical instrumentation and similar applications, particularly with regard to the broad and continuous spectrum of the light output.

The new μPAX-3 is the next generation 2-Watt Pulsed Xenon Light Source, with a smaller, more robust design that is 17% smaller than its µPAX-2 predecessor. State-of-the-art electronics and a precision aligned flashlamp are packaged into a single light source capable of providing broadband light in microsecond pulses with exceptional arc stability.

The µPAX-3 is an ideal solution for product designers and engineers developing small form factor analytical systems for point of care and field use applications such as medical analytics, water quality monitoring, environmental analysis and more.

Xenon flash lamps are confined arc flashlamps which produce microsecond to millisecond duration pulses of broadband light of high radiant intensities. Capable of operating at high repetition rates, these flashlamps generate light over a continuous spectrum from ultraviolet to infrared, at very high powers from 2W/25mJ to 60W/1J.
