I know this question has been asked before but a lot of people need assistance:
This FLUID SENSING video mentions and shows a plastic lens placed in front of the IWR1443BOOST to "narrow the field of view".
Please provide some details on this lens: dimensions (are the dimension high-precision?), material, ...
We wish to do level sensing and would benefit from a narrower field of view.
Our tank specs are: 7m height, 3m diameter, metal walls, granular material.
