Irradiance limit

Irradiance limit - static solutions - yellow and green

Notes:

  • Indicated irradiance limits are not based on measurements, but on validated numerical simulation, taking into account all properties of relevance.
  • The values apply for illumination by a 450 nm CW mode laser with tophat profile, and for good thermal contact of a heatspreader sized 20 x 20 x 4 to a heatsink at 30 °C.
  • For safety reasons stay at least 20 % below indicated irradiance limit. Accordingly, the values on this page may in no case be understood as technical product specifications, and are for general orientation purposes, only.

 

The blue laser light applied via a dichroic mirror blocks residual blue light, that is reflected from the sample.
