SPECTRUM AND APPLICATION BREAKDOWN
In general, Forensic and Alternate Light Sources emit high-intensity ultraviolet, visible and infrared light. Exposure to these types
of radiation, even if reflected or diffused, can result in serious, and sometimes irreversible, eye and skin injuries. Never aim the
light-guide at anyone. Never look directly into the light-guide or the optical parts of the instrument. Always wear appropriate eye
and skin protection when using ANY Forensic or Alternate Light Source.
