Monochromatic UVB light therapy for Psoriasis and Vitiligo skin diseases.

The EXCIMER ET- 308 system is a handheld system for intense monochromatic UVB therapy, treating autoimmune diseases of the skin such as Psoriasis and Vitiligo. Using a 308nm wavelength which replicates the wavelength of the excimer laser, EXCIMER ET- 308 allows you to treat patients quickly and effectively with the benefits of a lighter weight system that offers greater flexibility, lower investment costs, no consumables and greater ease of use.

  • Clinically-proven with effectiveness matching that of an excimer laser

  • Focused treatment with maximum protection of surrounding skin

  • Pain-free with no downtime

  • Compact, portable system

  • Cost-effective with low operation costs and maintenance-free technology



The 308nm wavelength is ideally suited for treatment of UV sensitive skin diseases such as psoriasis and vitiligo. The EXCIMER ET 308 system may also be used to treat other skin diseases that stem from immune system dysfunction. UVB radiation has an immune modeling effect which can normalize pathologically altered cellular activities. The ideal indications are persistent, localized lesions.

Before- After


The EXCIMER ET- 308 system uses a 308nm wavelength to effectively target skin lesions. The 16 cm² spot can be applied directly onto localized plaques, or masks may be mounted to adapt the spot size and shape to smaller areas. A variable power density ranges from 50 to 6,000 mJ/cm² and can be adapted to the needs of the individual patient. The system enables you to apply high, therapeutically-effective doses of monochromatic UVB light while leaving healthy skin unexposed and protected.
