Has anyone seen documentation or done optical power measurements for VL53L4CD? I’m trying to find the radiant energy or optical power output of this low power time-of-flight device.
(I only succeed to find a graph showing the relative emitted power in their datasheet)

When the device was certified as a Class 1 laser the needed to be tested and the total emitted power calculated.
So, ST has that number.
But they don't put it up on the web page. I think they are trying to keep the details quiet.
So here is what you do...
Go to ST.com and click on 'support'. From there you can open a trouble ticket and ask for the certification documentation.
Someone will send you the document.
It's mind-numbing to read and very difficult to completely understand, but somewhere in there is the number of micro-joules the laser emits.
