First select a product category. Here you can choose between linear encoders, angle encoders or length gauges.
Select the accuracy of the incremental length gauge that meets your requirements. You can choose between two accuracy classes, SPECTO for ±1 µm or METRO for ±0.5 µm.
The position detection can be incremental or absolute. The incremental measuring method provides a relative position as well as direction of movement, which requires an assignment to a reference point (starting point) at the beginning of the measurement. This is done by homing the axis. The absolute measuring method provides concrete position information at any axis position. A reference run at the beginning of the measurement is not necessary.
At this point you can select the type of bolt actuation. You can choose between two variants, spring-driven or pneumatic. With spring-driven length gauges, the built-in spring extends the measuring bolt into the measuring position and builds up the measuring force. The measuring bolt is extended in the rest position. On length gauges with pneumatic bolt actuation, the bolt extends when compressed air is applied. When the compressed air connection is vented, the built-in spring retracts the measuring bolt.

Semiconductor technology is engaged in the technical production of microelectronic components and assemblies, which are primarily made of semiconductor materials. Integrated circuits (ICs), manufactured from a semiconductor material such as silicon, are an important part of the production of modern electronic devices. Semiconductor production is a highly complex process that has to be continuously developed due to increasing demands on the performance of electronics. The demand for corresponding systems, machines and equipment increases from year to year.
High-precision positioning of axes is the key to many achievements of modern technology. Particularly in industrial semiconductor production or in the fields of medicine, research and inspection of materials, positioning tasks are becoming increasingly important. The challenges here are the constant miniaturization of assemblies, the highly accurate and reproducible measurement of translations, and the reliability of integrated systems.
Due to the very small size and modular design of the LIKselect optical linear measuring system from NUMERIK JENA, it is ideally suited for integration in very small, flat positioning tables.
In this example, two LIKselect measuring systems were integrated into a particularly flat cross table. This can be used for positioning components, wafers or production units. The LIKselect also offers the possibility to operate assemblies like a cross table in vacuum environments. This opens up new possibilities, especially in innovative and complex areas such as semiconductor technology or photonics.
The new platform design offers many advantages for users in a wide range of (metrology) applications such as quality assurance or production metrology.
