Hello,

I intended to use VL53L4CDV0DH in my project.

Could VL53L4CDV0DH measure reflective wafers material? 

Thanks

Chuong

I believe so.

But don't take my word for it. The P-Nucleo-53L4A1 is $56 and comes with everything you need to test. 

If you are successful, you are going to need this anyway, and if it fails, you are only out $56 and a few hours of test time. 

We guarantee that sensor will focus the camera in a cell-phone. That's what we invented it for. But people are using it for tons of applications that I could not even imagine. Easiest thing to do is simply try it. 

Really reflective materials generally return too many photons. So, we disable the vast majority of our photon detectors and carry on. If the material is specular (mirror-like) you might have an issue with angles. Too sharp an angle and the photons hit the target and bounce away. With no returning photons, we have no answer. 

But simply try it. Any limitations will become obvious.
