Underwater Calibration about afbr-s50-api HOT 4 CLOSED

I have limited experience with this sensor, but FWIW I am using 2mm cover glass and my sensor is pressed against the glass. Conveniently I don't need cover glass calibration because reflections off the cover glass from the transmitter (mostly?) cannot bounce into the receiver. When there is space between the sensor and cover glass then reflections can get into the receiver. I think it's better to avoid that if at all possible. Otherwise I'm of no help to your calibration questions.

Thanks for your answer Nathan.

Indeed, the need of xtalk calibration is less useful in this particular case.
Unfortunately in my application, I have a gap of about 0.5mm... Just above 0.1mm, where it is especially necessary.

And I sadly can't modify the air gap.

I guess you are referring to the recently released cover glass (AFBR-S50-Cover-Glass-Calibration-AN) and crosstalk calibration (AFBR-S50-XTK-Crosstalk-Guide) application notes? If not, please have a look. Of course, they do not cover underwater applications. But it should provide better understanding of the topic in general.

For now, we have only limited experience with underwater applications. So you maybe just need to test the results of your suggestions. Both approaches seem reasonable to me. If you can use the optical sink underwater, it should be possible to somehow run the calibration underwater too.

Anyway, as this is more a application support topic, please reach out to our TOF support team for a better and more detailed help. I am sure we can figure out an reasonable approach.

Yes, I was referring to the application notes.

Thanks for your suggestions.
