The high-precision surfaceCONTROL 3D 3500 snapshot sensor enables automated optical inspection of shape, geometry and surfaces diffuse reflective surfaces. It has a compact design and enables high data processing speed with improved accuracy. With its z-axis repeatability up to 0.25 µm, it redefines the standard in high-precision inline 3D measurements. Even the smallest deviations in height and flatness can be reliably detected. It has two models that cover different measurement fields.

Gigabit Ethernet enables high-speed data transfer, while the 2D/3D Gateway II supports PROFINET, EtherNet/IP, and EtherCAT connections. The sensor also has a digital I/O interface. Advanced software tools allow for precise surface inspections and 3D measurements. The system is compatible with GigE Vision, enabling seamless integration with third-party image processing software. There is also an SDK for seamless customer integration.
Application Examples
- 3D geometry inspection and form detection
- Inspection of electronic components
- Defect identification
- Inspection of form, position, and surface
- 3D text recognition and detection of extremely fine structures
