VL53L3CX Laser Rangefinder Module

Description:

VL53L3CX combines high-performance proximity and ranging sensors with multi-target distance measurement and automatic smudge correction functions. The miniature reflowable package integrates a single photon avalanche diode (SPAD) array and physical infrared filter to achieve the best ranging performance under various ambient lighting conditions, and is equipped with various cover glass windows. The VL53L3CX combines the advantages of a high-performance proximity sensor, excellent short-distance linearity, and distance measurement capabilities up to 3 m. VL53L3CX can also detect different objects in the field of view (FoV) through deep understanding. Allows the crosstalk immunity of the cover glass to exceed 80 cm, and has a dynamic smudge compensation function.

Application:
Service robots and vacuum cleaners (wall following and fast obstacle detection)
Sanitary (robust user detection whatever the target reflectance)
Smart buildings and smart lighting (user detection to wake up devices)
IoT (user and object detection)
Laser assisted autofocus (AF): enhances the camera AF system speed and robustness, especially in difficult scenes (low light and low contrast); ideal
companion for phase-detection autofocus (PDAF) sensors.
Video focus tracking assistance
