Absolute distance measurement with nanometer resolution

The IMS5400-DS is used for high-precision displacement and distance measurements. Unlike conventional interferometers, the IMS5400-DS also enables stable measurement of step profiles. Thanks to the absolute measurement, the scanning of steps is performed with high signal stability and precision. When measuring on moving objects, the differences in height of heels, steps and depressions can thus be reliably detected.

Multi-peak distance measurement

With multi-peak distance measurement on transparent objects, up to 14 distance values are evaluated simultaneously. For example, the distance between glass and a carrier plate can be determined. In addition, the controller can calculate the glass thickness based on the distance values.

Ideal for industrial environments

Robust sensors and a controller in a metal housing make the system ideally suitable for integration into production lines. The controller can be installed in the control cabinet via DIN rail mounting and provides very stable measurement results due to active temperature compensation and passive cooling. These compact sensors are extremely space-saving and can also be integrated in confined spaces. Highly flexible fiber optic cables are available in lengths up to 10 m and allow a spatial separation of sensor and controller. Commissioning and parameterization are conveniently performed via web interface and do not require any software installation.

Small light spot for the smallest of details and structures

The sensors generate a small light spot over the entire measuring range. The light spot diameter is only 10 µm and allows the detection of small details such as structures on semiconductors and miniaturized electronic components.

Measuring multiple surfaces

The interferometric measuring method enables measurements on numerous surfaces. This allows high-precision distance measurements on reflecting metals, plastics and glass.

NEW: Sensors also with 90° beam path

Due to their compact size, these sensors can also be integrated into restricted spaces. In particular, the models with 90° beam path require significantly less required installation space.

Interface and signal processing units

Modern interfaces for integration into machines and systems

The controller offers integrated interfaces such as Ethernet, EtherCAT and RS422 as well as additional encoder connections, analog outputs, synchronization inputs and digital I/Os. When you use Micro-Epsilon's interface modules, PROFINET and EthernetIP are available. This allows the interferometer to be integrated into all control systems and production programs.
