π-Photon: New Generation Compact UV Source
π-Photon is a novel microplasma-based ultraviolet source that combines high power, exceptional uniformity, and versatility in a compact modular form factor.
Available emission wavelengths: 172 nm, 222 nm, 308 nm.
All-In-One Construction
Efficient light source, integrated power supply, passive cooling, and internal purge system means that everything needed for operation is contained in the system itself. Just plug in the included 12 V power adapter, connect to a purge-gas source with the 1/4" quick-connect fitting (purging is required for 172 nm systems only), and the π-Photon is ready for use.
