3D surface sensors with new measuring range for inspecting small objects and surface defects with repeatability from just 0.25µm

Precision sensor manufacturer Micro-Epsilon has extended its surface control range of high precision 3D snapshot measurement sensors for automated, inline measurement of geometry, shape and surface quality of objects. The surfaceCONTROL SC3xx0-30 offers a smaller measuring field of 30 mm x 18mm with Z range of 12mm. The sensor delivers the measurement results at a z-axis distance of between 124 and 136mm.

The combination of small measurement area and high resolution allows for point spacing from 16 µm in the XY directions, whilst the Z resolution impresses further with just 0.7µm. The surfaceCONTROL 3xx0-30 detects even the finest 3D and surface structures with the utmost precision and reliability. With high repeatability of <0.25 µm and a high data processing speed of up to 2.2 million 3D points per second, the sensor sets a new benchmark in high precision 3D measurement technology.

The new 30 mm measuring range is available in all classes and models of the surfaceCONTROL SC3xx0 series, i.e. the surfaceCONTROL 3D 3200 and surfaceCONTROL 3D 3500 ranges, with each offering a different measuring area. Both models are fully integrated industrial sensors that are protected to IP67 with passive cooling (active cooling is available for higher operating temperatures).

The surfaceCONTROL SC35xx-30 is suitable for a wide range of flatness measurement, coplanarity measurement and surface defect detection applications, including flatness inspection of circuit boards; planarity inspection of unpopulated PCB substrates; completeness check of electronic components on fitted PCBs; 3D measurement of high precision mechanical parts; width, tilt angle and position measurement of rivets; detection and evaluation of breaks on clutch discs; 3D text recognition of embossments that cannot be solved using 2D image processing due to lack of contrast; inspection of height and thickness of adhesive beading on smartphone shells; and determination of shape deviation defects on injection moulded parts.

Ease of integration

All surfaceCONTROL 3D systems support the very latest GigE Vision and GenICam standards for easy integration into third-party image processing software. A comprehensive software development kit (SDK) is also provided that allows customers to develop their own analysis software. Also included in the scope of supply is Micro-Epsilon’s 3D Inspect software, which offers a convenient user interface for surfaceCONTROL sensors. The software allows fast commissioning, evaluation of the sensor, set up and optimisation of parameters, and ensures the correct positioning of the measuring object.
