Beyond its rugged housing, the device boasts a compact 3mm working distance and a tiny 15-micrometer light point diameter. These fine specifications support high-precision inline tracking directly inside the host machine.
Advanced Capabilities and Multi-Layer Tracking
Driven by the IMS5420 controller, the system employs a broadband superluminescent diode spanning a 1,100nm wavelength range. This configuration enables a single measuring setup to effortlessly evaluate undoped, doped, and highly doped silicon wafers.
Unmatched Resolution and Industrial Integration
The interferometer achieves an impressive z-axis resolution of less than 1nm while supporting measuring rates up to 6kHz. This speed makes it ideal for rigorous inline and at-line quality control frameworks.
An optional multi-peak variant is also available to simultaneously track up to five distinct layers, including complex air gaps and coatings. Configuration is simplified through an intuitive web interface backed by robust industrial communication protocols like EtherCAT and Profinet.
