VL53L1X reflectance targets?

[mdmottola]

Prior to the forums being migrated, I saw a post linking to sites to obtain reflectance targets for calibrating and testing the VL53L1X or VL53L0X. I.e. Grey 17% N4.74, Grey 54%, and White 88% N9.5.

I'm moving from breadboard development with the satellite boards to a PCB with the VL53L1Xs sensors populated on them and calibration will become a necessity. I've attempted searching the new forums for this post without much luck. Could anyone direct me to where to obtaining these reflectance targets?

Nm was able to find the post just now; must have been migrated recently:
