VCSELs have special properties in contrast to other typical laser sources. As a result, VCSEL eye safety evaluation is more complex and a couple of additional aspects have to be considered that would not apply for "normal" lasers. Consequently, the validation of a VCSEL's laser class is not trivial, and even more so because an easily understandable guideline for the assessment of VCSEL safety has not yet been published.
In this presentation, Katharina Predehl of Instrument Systems will guide you through:

  •     VCSELs in 3D Sensing Applications
  •     Laser Eye Safety
  •     Laser Safety: The IEC60825-1 Standard
  •     Laser Classes
  •     VCSEL Beam Geometry
  •     Laser Class Assessment: Flow chart
