TeraRanger Duo



The TeraRanger Duo is a powerful surface detection solution for any environment!


Combining our advanced infrared Time-of-Flight (ToF) technology with classic ultrasound technology, you’ll never again have issues detecting the proximity of difficult surfaces. Whether it’s reflective, transparent or absorbent surfaces such as carpets, water, transparent glass, or sound absorbing materials.  TeraRanger Duo will provide fast, accurate results in a super-light and cost-effective package.

Featured Use case: TeraRanger Sensors against glass surfaces

We often get asked whether our infrared Time-of-Flight distance sensors can detect glass and other transparent surfaces. And to many people’s surprise, the answer is “yes”. Clearly, there are somecaveats, but you can read about those in this short white paper.
