Measurement conditions

In all measurement tables of the document, it is considered that:

1.

The full field of view (FoV) is covered (typically 25 ° is covered)

2.

Charts used as targets are: grey (17 % reflectance, N4.74 Munsell) and white (88 % reflectance N9.5

Munsell)

3.

Nominal voltage (2.8 V) and temperature (23 °C)

4.

The device is controlled through the driver using the default settings (refer to the user manual for driver

settings description).

5.

Indoor (no IR) means there is no contribution of light in the band 940 nm ± 30 nm. Outdoor overcast

conditions means an illumination level of 0.7 W/m² back on the sensor, in the band 940 nm ± 30 nm.

6.

No coverglass is present

7.

Typical samples used

5.2

Minimum ranging distance

A target can be detected down to 10 mm.

5.3

Maximum ranging distance

The table below shows the ranging specification for the typical device bare module, without cover glass, at room

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

Target reflectance level,

full FoV (reflectance %)

Indoor (detection rate %)

Outdoor overcast (detection rate %)

White target (88 %)

Typical: 310 cm @ 94 % min.

Minimum: 310 cm @ 50 % min.

Typical: 100 cm @ 94 % min.

Minimum: 110 cm @ 50 % min.

Light gray target (54 %)

Typical: 290 cm @ 94 % min.

Minimum: 290 cm @ 50 % min.

Typical: 70 cm @ 94 % min.

Minimum: 90 cm @ 50 % min.

Gray target (17 %)

Typical: 170 cm @ 94 % min.

Minimum: 200 cm@ 50 % min.

Typical: 70 cm @ 94 % min.

Minimum: 90 cm @ 50 % min.

Note:

In the table above:

•

"Indoor" corresponds to no infrared

•

"Outdoor overcast" corresponds to a parasitic noise of 10 kcps/SPAD for the device module. For reference,

chart at 40 cm.

•

Detection rate is the worst case percentage of measurements that return a valid measurement.

•

The ranging distances reported are the ones reported by the driver by the parameter called RangeMilliMeter.
