Hi team,

The customer would like to use OPT8241. He needs to get the min distance that OPT8241 can measure.

Would you help me?

Mickey,

Sorry for delaying this. OPT8241 does not have a minimum operating distance fundamentally. It is limited by practical considerations like size of lens, separation between lens and LED/laser, etc. It is possible to design a system which can measure a few cm of distance.

Can you tell us the minimum distance requirement of the customer?

Regards,
Subhash

Hi Subhash,

Thanks for your reply. I will confirm with the customer for his requirements.

Can I recommend 3D ToF System Estimator Tool ?

Hi Mickey,

Yes, you can recommend 3D ToF System Estimator tool. But that tool does not model laser-to-lens distance as a limit for near range limit.
