Excimer Lamps and Modules
Unique VUV 172 nm radiation: Your irradiation source for plastic surface treatment.
To achieve the best results irradiation of plastic surfaces, USHIO provides custom-ized VUV excimer solutions. Chemical bonds that cannot be broken using standard UV lamps can be dissolved using the VUV 172 nm wavelength produced by excimer lamps.
Applications: • Surfaceactivation• Removalofcontaminatesfromproductionprocesses• Adhesionimprovement• Opticalbonding
Advantages:• Inducedfastandefficientprocess• Nocontamination• Nochemicals• Instanton/off• Narrowbandwidthradiation• “Cold”radiation• Environmentallyfriendly• Easytoimplement
The very unique VUV 172 nm excimer radiation can be used in a multitude of potential applications in which surface energyenhancementandaselectivesurfacemodificationis needed. The enhanced surface energy leads to better attachment of inks, coatings and lacquers on surfaces and therefore increase product quality.
The incorporated excimer lamps are a special source of highly energetic ultraviolet radiation: VUV radiation at 172nm. The spectrum is generated by their filling containing noblegases or noble-gas halogen compounds. Besides chang-ing their filling the radiation spectrum can be adjusted by special phosphors. During their long lifetime lamps are highly efficient,upto67%.
Instant on/offat full radiationoutput allows immediatepro-cesses. Our unique VUV excimer lamps are ‘cold’, which meansthereisnoIRemission.ForplasticsurfacetreatmentUSHIO provides a broad range of various lamp lengths and outputs from 55mm and 9W up to 2200mm and 4kW.

Application examples
The printed image on the untreated card is blurry and even cannot be read by scanner systems, while the image on the treated card is sharp and uniform.
