2) OSL Reader
  • OSL reader is a light leakage free, precisely fabricated mechanical assembly, that houses ultra-fast and ultra-sensitive SEEKER detection module with detection filter basket, Light stimulation assemblies (four) diagonally placed around detector module inside the cylindrical enclosure.
  • Light source can be of following wavelengths: 460-470nm or 520 – 535 nm or both based on the sample to be irradiated. The electronic circuits built-in provides constant current drive to each of the LED clusters with power control, to vary the luminous intensity. Proper heat sink and optical feedback should be present to ensure the stable light output. The output power density at the badge reader should be nearly 80 mW/cm2.
