For the first time, the IDS3010 unites exceptional interferometric precision with integration-friendly dimensions. The sensor is also compatible with different fieldbus worlds and – thanks to the integrated web server – ready to use in Industry 4.0 applications.

Measurement directly on the target: contactless and extremely precise
The IDS3010 is a contactless interferometric sensor which enables highly precise measurements of positions and motions. It provides 10-12 m position resolution – in other words, one picometer or one billionth of a millimeter – and achieves working distances of up to 5 meters! If suitable sensor heads are fitted, it can even perform measurements over a 30 meter distance. The IDS3010 measures directly on the target, for example a workpiece, a tool or a machine component. Inherent or mounting-related measurement errors due to backlash, wear, deformation, thermal expansion or other influences – which are intrinsic to indirect measuring glass scales as well as inductive displacement sensing systems – are completely eliminated. Stationary or moving targets are sensed at velocities of up to 2 m/s with a data acquisition bandwidth of 10 MHz – one measurement containing all relevant information on the position or movement is generated every single microsecond.

Simultaneous measurement in up to three axes on all kinds of surfaces
The IDS3010 is designed as an optical, multi-channel measuring sensor. Up to three miniature sensor heads can be connected via glass fiber cables to the ultra-compact basic unit, which measures just 19.5 × 5 × 5 cm, in order to simultaneously measure positions and motions in up to three axes. The sensor heads can be supplied with optics of different types for measurements on all kinds of materials and surfaces such as glass, plastic, ceramic, aluminum, copper or steel. Customized sensor heads, for example made from tungsten or sapphire, are likewise possible for particularly complex measurement tasks.

Industrial grade, integration-friendly connectivity
The IDS3010 has an integrated web server. The sensor alignment, initialization and configuration can thus be controlled, adapted and monitored remotely from any location. The sensor can also be integrated in Industry 4.0 applications. At the same time, a broad spectrum of real-time interfaces and protocols allows position data to be transmitted easily to CNC controllers or RTOS computers. Fieldbus interfaces to standard industrial networks like CAN open, Profinet, Profinet RT or EtherCAT can be provided on request, allowing the IDS3010 to be integrated into bigger systems without any problems.

Industrial grade interferometry opens up innovative applications
Not only semiconductor manufacturing and productronics but increasingly also drive technology and precision machines demand sub-nanometer precision as a precondition of successful miniaturization and increased power density. The range of applications for the IDS3010 is accordingly very wide. As a pure displacement sensing system, it can be used among other things to calibrate machine tools and coordinate measuring machines. In adjustment units of the kind employed in the precision mechanics and optics industry or in high performance special-purpose machinery, the IDS3010 is ideal for position counting as an alternative to incremental encoders. In a multi-channel configuration, the sensor – together with suitable actuators – functions as a vibrometer to actively compensate vibration in real-time. Mechanical eccentricity shift due to wear or the application of forces can be determined on rotating targets. Runout of high speed shafts, for instance, can be measured and its exact angular position determined.

The IDS3010 measure positions directly on the workpiece. The sensor rules out measurement errors due to elasticity or wear in guides and bearings, or to the influence of thermal expansion and machine deformation.

Up to three sensor heads can be connected to the IDS3010. It is thus possible to measure not only the linear movement of a target but also runout errors such as axial and radial offset, yaw, pitch and roll or out-of-roundness and eccentricity of rotationally symmetric parts.

The IDS3010 can be operated with different sensor heads: ultra-compact heads for the most confined spaces or alternative designs where priority is given to easy alignment or to compatibility with a variety of target materials (glass, aluminum, ceramic, etc.).
