The Gemini 435Le is Orbbec’s newest 3D camera, designed to deliver robust, high-precision depth sensing for demanding industrial and outdoor robotics environments. Engineered with industrial-grade construction and IP67 protection, it supports logistics automation, robotic arms, and autonomous mobile robots operating in variable and dynamic conditions.

The system employs stereo vision technology with a 95 mm baseline and projects infrared patterns using a vertical cavity surface-emitting laser (VCSEL). This laser diode module enhances the visibility of low-texture surfaces, with an 850 nm ±6 nm wavelength and compliance with Class 1 safety standards. The unit features a horizontal field of view (FOV) of 101°, vertical FOV of 72.5°, and a ±3.0° tolerance, maintaining reliable depth coverage across broad scenes.

The Gemini 435Le includes a single-point direct time-of-flight (dToF) laser ranging module, operating at 940 nm to enhance performance in close-range and blind-spot detection. This module features a 19° projector FOV and a 37° receiver FOV, offering ±15 mm accuracy at 1–100 mm range. Accuracy improves to ±10 mm at 100–200 mm and ±5% at 200–400 mm.

The infrared and RGB modules each support 1280 × 800 resolution with a 16:10 aspect ratio, global shutter, fixed focus, and shared FOVs of 94° (H) × 68° (V), with a diagonal FOV of 104°. Both modules are designed to minimize distortion, keeping it under 1.5%, with FOV tolerances within ±3.0°. The IR module includes a visible + NIR-pass filter, while the RGB module uses an IR-cut filter.

An onboard 6-DoF IMU provides real-time inertial data with synchronized timestamps across IMU, IR, RGB, and depth streams. The gyroscope and accelerometer each operate on a 3 × 16-bit format. The gyroscope supports ±17.45 rad/s (1000 dps), while the accelerometer supports ±39.2 m/s² (4g). Both sensors support sampling rates from 50 Hz to 1000 Hz. A dedicated temperature sensor monitors operating conditions from -40°C to 85°C.
