There is an article I wrote - actually on this page, but in the Knowledge base.

That Hornix was co-designed by ST and Hornix. Built specifically for customers like you.
Glass, acrylic (PMMA) and Polycarbonate are all good choices.
Close, Clear, Clean, Thin (I could not think of a 'C' word meaning thin) are the traits you are looking for.
Putting an opaque barrier between the Tx and Rx guarantee no crosstalk even in the presence of fingerprints and condensation. (Crosstalk is the light that goes from the TX side to the RX side without hitting your target. ) The Hornix glass gives you choices. The expensive one has the barrier, but it does cost more.
That document is valid for all the ToF sensors.
