VL53L0 is a new generation Time-of-Flight laser-ranging module housed in the smallest package on the market today setting a new benchmark in ranging performance levels.

VL53L0 can measure absolute distances, beyond 2m, independent of target reflectance in less than 30ms. The VL53L0 is based on Time-of-Flight principle coupled with a leading-edge SPAD (Single Photon Avalanche Diodes) array and implementing ST’s second generation FlightSenseTM patented technology.

The VL53L0’s 940nm VCSEL emitter (Vertical Cavity Surface-Emitting Laser), is totally invisible to the human eye and when coupled with physical Infrared filters enables longer ranging distance, higher immunity to ambient light and better robustness to cover-glass optical cross-talk.
