The VL53L1X is our longest ranging Time of Flight (ToF) sensor with a reach of up to four meters (about 13 feet). Despite doubling the range of the VL53L0X, the newer part is still a tiny module. Indeed, the VL53L1X has a 4.9 mm x 2.5 mm x 1.56 mm package, whereas the VL53L0X measures 4.4 mm x 2.4 mm x 1.0 mm, making it the smallest four-meter ToF sensor on the market. We decided to keep both devices to help designers choose the most appropriate component for their product. Those that don’t need the extra distance can profit from a smaller and more affordable solution while the engineers that do require more performance still have the assurance that the VL53L1X builds on everything we learned with the VL53L0X.
Since its launch in 2016, the VL53L0X has remained the world’s smallest time-of-flight sensor thanks to leading edge in-house packaging technology that enables the integration of a custom VCSEL (Vertical-Cavity Surface-Emitting Laser) and its driver, a SPAD (Single-Photon Avalanche Diode) receiver, and all the required circuitry in an all-in-one module. It was even one of the highlights of our 2017 Developers’ Conference, while the VL53L1X received the Gold Level Innovation Award a few weeks ago at the Sensors Expo and Conference. Indeed, the new part is quite popular because it retains so many of the original features of the previous component and builds on them to significantly increase performance. Hence, with so many third-party companies selling breakout boards integrating our latest model, and third-party products relying on our technology, we thought it was important to dive into three of the major features that explain the success of the VL53L1X.
