TOF Lens Solutions
TOF Lens for 3D Depth Sensing Cameras
High-precision TOF lenses optimized for 850nm and 940nm infrared illumination, enabling accurate depth sensing for robotics, automation, logistics, and smart devices.
What Is a TOF Lens?
A TOF (Time-of-Flight) lens is an optical lens specifically designed for depth sensing cameras that measure the travel time of emitted infrared light.
The lens captures reflected infrared signals and projects them onto a TOF sensor, enabling precise 3D depth measurement in real time.
TOF lenses are widely used in robotics, autonomous systems, warehouse automation, facial recognition, and industrial inspection.
How TOF Imaging Works
The accuracy of TOF measurement depends heavily on lens distortion, infrared transmission efficiency, and optical consistency.
Key Requirements for TOF Lenses
850nm vs 940nm TOF Lenses
| Feature | 850nm | 940nm |
|---|---|---|
| IR Power | Higher | Medium |
| Ambient Light Resistance | Lower | Higher |
| Outdoor Performance | Moderate | Excellent |
| Eye Safety | Good | Better |
| Consumer Electronics | Common | Very Common |
| Robotics | Good | Excellent |
940nm TOF lenses are increasingly preferred in robotics and consumer electronics because they offer stronger ambient light suppression and improved eye safety.
