5 Ranging performances
5.1 Measurement conditions
In all the measurement tables of this document, it is considered that:
• All ranging performances are measured with the target covering the full FoV.
• Charts used as targets are: gray (17% reflectance, N4.74 Munsell) and white (88% reflectance N9.5
Munsell).
• Nominal voltage is 2.8 V and temperature is 23°C.
• The device is controlled through the driver using the default settings (refer to the user manual for driver
settings description).
• Indoor (no IR) means there is no contribution of light in the band 940 nm ± 30 nm
• Outdoor overcast corresponds to an ambient light level of 10 kcps/SPAD. For reference, this corresponds to
a 1.2 W/m
2
at 940 nm following the AM1.5G spectrum and is equivalent to 5 kLux daylight as reflected by a
gray 17% chart at 40 cm.
• No cover glass is present.
• Typical samples are used.
• Offset correction made at 100 mm from sensor with gray 17% target.
5.2 Minimum ranging distance
The minimum detection distance is 0 mm. The minimum ranging distance with a linear response is 1 mm.
5.3 Maximum ranging distance
The following table shows the ranging specification for the VL53L4CD bare module, without cover glass, at room
temperature (23°C), with nominal voltage (2.8 V) and full FoV covered.

(detection rate %)
White target (88%)
Typical: 1200 mm @ 90% min
Typical: 1300 mm @ 50% min
Typical: 550 mm @ 90% min
Typical: 600 mm @ 50% min
Gray target (17%)
Typical: 450 mm @ 90% min
Typical: 475 mm @ 50% min
Typical: 400 mm @ 90% min
Typical: 450 mm @ 50% min
Detection rate is a statistical value indicating the worst case percentage of measurements that return a valid
ranging. For example, taking 1000 measurements with 90% detection rate will give 900 valid distances. The 100
other distances may be outside of the specification and are flagged with an error status.
