Characterization of VCSELs for 3D Sensing Applications According to the IEC60825-1 Standard
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 it is even more important because an easily understandable guideline for the assessment of VCSEL safety has not yet been published.
In this presentation, 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.
