Ranging accuracy definition

The figure below illustrates how range accuracy is defined over distance.

Figure 18. Ranging accuracy vs. distance

The ranging accuracy is a direct evaluation of the measurement error, including offset errors and output noise. At

least 90% of the ranging values are within the declared ranges. This quality indicator includes measure-to-

measure and part-to-part dispersion.

Ranging accuracy at nominal temperature

The following table shows the ranging accuracy for the VL53L4ED bare module. This is without a cover glass, at

room temperature (23°C), with nominal voltage (2.8 V), and the full FoV covered.
