STMicroelectronics' VL53L1X is a state-of-the-art ToF laser-ranging sensor, enhancing the ST FlightSense product family. It is the fastest miniature ToF sensor currently on the market with accurate ranging up to 4 m and fast ranging frequency (up to 50 Hz). Housed in a miniature and reflowable package, it integrates a single photon avalanche diode (SPAD) receiving array, a 940 nm invisible laser Class 1 emitter, physical infrared filters, and optics to achieve the best ranging performance in various ambient lighting conditions with a range of cover window options.

It is easy to integrate into devices, allowing creative ID since it can be hidden behind various cover window materials and colors. Unlike conventional IR sensors, the VL53L1X uses ST’s latest generation ToF technology which allows absolute distance measurement whatever the target color and reflectance. It is also possible to program the size of the ROI on the receiving array, allowing the sensor FoV to be reduced.
