Teradek TOF.1 Precision Infrared Laser Range Finder

The Teradek TOF.1 is a compact, lightweight infrared rangefinder designed to deliver real-time distance measurements between a subject and the camera’s focal plane. Engineered for seamless integration with the Teradek RT system, TOF.1 connects via a single motor cable to the MDR.X Lens Control Receiver, enabling distance readouts on CTRL.1, CTRL.3, and CTRL.5 wireless controllers, as well as SmallHD monitors running PageOS 4 or later. With a hyper-accurate IR sensor and a 3° field of view, TOF.1 detects subjects up to 80 feet away and refreshes measurements 60 times per second, allowing for responsive autofocus and precise lens motor adjustments. A proprietary smoothing algorithm ensures fluid transitions without jitter, while the detachable laser sight helps operators visually align the sensor’s field of view. The system supports customizable overlays on SmallHD monitors, giving camera assistants critical follow-focus data directly on screen. TOF.1 mounts easily via a ¼-20 thread and weighs just 125 grams, making it ideal for compact rigs, drones, and gimbals. Whether tracking fast-moving subjects or executing complex focus pulls, TOF.1 delivers unmatched precision and control in a truly minimal form factor.
