ELWIMAT®-Wedge
Wedge angle measuring device for highly precise optical measurement technologyThe ELWIMAT®-Wedge wedge angle measuring device from HOFBAUER Optik is the ideal solution for precise wedge angle measurement and parallelism testing in optical production metrology. Thanks to powerful ELWISOFT software, high-resolution subpixel evaluation, and a flexible system design, the measuring system offers the highest accuracy and process reliability – both in the laboratory and in serial production.
Maximum precision in reflection & transmission
→ Safe measurement from 0.0001° wedge angle – even with extremely small tolerances.Thanks to two highly specialized measuring methods (reflection with double cross image and transmission), both large and extremely small wedge angles are reliably detected and documented. The subpixel evaluation ensures the highest resolution with reproducible accuracy.
Powerful ELWISOFT software
→ Intelligent, automated evaluation with documentation and mapping.ELWISOFT offers various modules for reflection and transmission measurement, automatic wedge angle evaluation, mapping for linearization, and even calibration routines. This enables complete quality assurance directly in the measurement process.
Modularity & flexibility in system design
→ Scalable for every application – from laboratory to serial production.Depending on the task, the system can be expanded with various accessories such as angle converters, certified wedges, touch modules, or rotary tables. This allows the equipment to be perfectly adapted to growing or changing requirements.
Industry 4.0 ready – Process integration included
→ Digital networking, automated testing processes, and complete traceability.With USB 3.0 connection, automated routines, and documentable measurement series, the system meets all requirements for a modern, connected manufacturing environment. Ideal for production lines that demand the highest efficiency and transparency. Particularly suitable for:
- Wedge angle measurement of optical components (0.0001° to 6°)
- Radius measurement of cylindrical lenses and prisms
- Alignment of opto-mechanical assemblies
- Inline process monitoring and quality assurance
- Calibration testing of autocollimators
