VL6180X measurement in a tube (FoV change?)

We'd like to measure distance in a tube with VL6180X. Tests with a diameter of approx. 5 cm show that the max. distance is reduced and the sensor is underranging. That is probably because the sensor receives some light reflected from the side walls. ...

Resolved! VL53L1X reduced FoV

According to the docs I've read maximum FoV using 16x16 SPADs is 27 degrees and minimum FoV using 4x4 SPADs is 15 degrees. But if my math is correct, when side of the measured area is 1/4th then the FoV should be approx. 6.7 degrees. Aren't the SPADs...

VL53L1X MBED Library ?

I just got the VL53L1X ToF sensor and I have a k64f board using ARMmbed. I have been searching all day long, but I could not find a library for the board for mbed, does anyone know if there is any library available for this sensor on mbed?

Resolved! I was wondering if it would be possible to add a lens system to the sensor and focus the emitted light and reduce the field of view.

I feel this would solve a couple problems. First, it would allow for more energy to be returned to the detector, increasing the signal to noise ratio and second, it would allow customers to focus on more specific areas. My questions are - can this be...
