Functional description

The device emits UV light at a wavelength of 365nm by a light emitting diode (LED). The LED operates
in continious mode. The light gets homogenized and shaped by a Köhler beam path to a flat top
intensity at treatment position. The user operates the device by buttons and an LC display. The
device contains interfaces for attaching the power supply, UV meter for measuring the illumination
intensity and stand parts for mechanical attachment.

The dev

ice is no sterile product and has no sterile components. It doesn’t emit radioactivity.

The user and third parties will come in contact with the device and its materials like aluminium,
stainless steel, thermoelastic plastic.

For further information about technical specifications and mechanical characteristics see chapter 5.1.
