Extended range (>100mm)

3.2.1

Extended range conditions

Ranging beyond 100 mm requires a low cross-talk system, use of a gasket, small air gap

(below 1 mm) and cover glass with IR filter (transmission >80% @ 850nm and <15% @

450-700nm). Tuning of the following parameters are required:



SNR limit



Convergence threshold



Max convergence time



Factory calibrated ambient window calibration settings applied by the host

3.2.2

Max range vs. ambient light level

Table 15 shows the worst case maximum range achievable under different ambient light

conditions. No cover glass was used in these tests. The device was tuned as per

recommendations in Section 3.2.1. The minimum detection rate is the worst case

percentage of measurements that will return a valid measurement.
