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.

A New Processing Regime

The low output power of traditional VUV and far-UVC sources has prevented the widespread use and application of these wavelength, both in research and production environments. The π-Photon overcomes this barrier and is revealing the true power of UV - driving new chemistries, reaction regimes, and processing techniques. Ultraviolet is not just for photolithography and curing anymore!

A New Way to Think of Power

UV arc lamps provide high average power. Excimer UV sources provide high photon flux. The π-Photon provides both high average power and high photon flux - without the need for active or external cooling. This unique combination of high power and high photon flux is harnessed in a package that fits in the palm of your hand, yet drives large-area reactions and processes not achievable by other light sources.

A New Form Factor in Lamp Technology

The heart of each π2-Cygni is a planar microcavity discharge lamp. Broad-area emission provides superior uniformity compared to traditional arc-discharge lamps, while simultaneously eliminating the need for complex condensing, collimating, and homogenizing optics

Ultraviolet is Now Green

Prior to the π-Photon, ultraviolet light production typically meant toxic materials, low conversion efficiency, and high equipment cost. π-Photon smashes these barriers by providing a solution which is environmentally friendly and energy efficient. No toxic materials are utilized in the manufacture and construction of π-Photon, and the utilization of π-Photon in production processes provides potential for reducing chemical waste streams and water consumption. All at a fraction of the cost of other VUV/far-UVC sources.
