Specifically designed for long-range, multitarget measurements, the VL53L4CX provides very accurate distance measurements up to 6 m with excellent results over short distances. A new generation laser emitter with 18° FoV improves performance under ambient light. Thanks to ST's patented algorithms and innovative module construction, the VL53L4CX is also able to detect multiple objects within the FoV with depth understanding. ST histogram algorithms ensure cover glass crosstalk immunity beyond 80 cm and dynamic smudge compensation for targets below 80 cm. Like all Time-of-Flight sensors based on ST's FlightSense technology, the VL53L4CX records an absolute distance measurement regardless of the target color and reflectance. Housed in a miniature reflowable package, which integrates a SPAD (single photon avalanche diode) array, the VL53L4CX achieves the best ranging performance even when hidden behind a wide range of cover glass materials. All of ST's Time-of-Flight sensors integrate a VCSEL (vertical-cavity surface-emitting laser) which emits a fully invisible 940 nm IR light, which is totally safe for the eyes (Class 1 certification).
