, “Cleaning the LED Head”.
The outer lens frame of the UV LED Head includes an optical window assembly. Improper handling and
cleaning practices can damage polished surfaces or coatings which are utilized in this optical window. Note that
damage to the surface of the glass or coating can degrade the unit’s performance. Proper handling and cleaning
technique is very important. Below are the recommended procedures for cleaning of the OmniCure® UV LED
Head optical window.
Always handle the UV LED Head by the metal enclosure; never touch the optical window with your fingertips.
The moisture or oils on your fingertips can damage the coating of the lens window. Fingerprints left on an
optical surface for an extended period of time, can become a permanent stain. Even if you are wearing gloves,
avoid touching the optical surface.
Never handle the optical window with metal implements or tweezers.
Do not place the UV LED heads lens assembly onto a hard table-top surface; this can cause scratches in the
window surface.
To store UV LED heads, wrap them individually in a clean, lint free bag and store in a safe place.
Never store unwrapped LED Heads together in a box or bag, as they may become damaged if they come in
contact with each other.
