Luminescence sensors

UV Luminescent Sensor with Analog and Digital Dual Outputs

The SMARTEYE® STEALTH-UV™ is a special purpose luminescence sensor designed to detect the presence of invisible fluorescent materials contained in special chalks, inks, paint, greases, glue, optical brighteners found in labels, paper, tape, string, etc. The STEALTH-UV luminescence sensor contains an ultraviolet (UV) solid state light source that is used to excite the luminescence in materials to fluoresce in the visible range. The sensor's detector then responds to the visible fluorescing light. When the received fluorescing light level as displayed on the Contrast Indicator reaches a level of "4" or above, the NPN and PNP output transistors will switch to the opposite state.

Typical Digital Verifications

  • Detection of tamperproof seals or labels
  • Detection of invisible registration marks
  • Product Inspection/Verification

Analog/Digital Process Control

  • Monitoring
  • Controlling
  • Gluing


  • Digital and Analog Outputs in one sensor
  • Sense difference between low UV Contrast Levels
  • Four Set Points
  • Fiberoptic Models
