ELWIMAT®-VFS 4000
4D measurement system for precise alignment of beam axes and componentsThe ELWIMAT®-VFS 4000 is based on the innovative vignetting field diaphragm method and provides precise 4D measurement (2× angle, 2× position) in a compact system. It is ideally suited for alignment, calibration, and monitoring of optical components and systems—especially in laser and instrumentation technology.
Simultaneous measurement of angle & position
With the ELWIMAT®-VFS 4000, angles (in two axes) in the arcsecond range and position deviations in the micrometer range can be simultaneously measured—using just one measurement process. This saves time, increases precision, and minimizes misalignments in optical systems.
Maximum accuracy with high flexibility
Thanks to its opto-electronic design, the system is freely positionable and offers high reproducibility even at long working distances. Tolerance fields can be displayed live in the camera image—complete with color change when limits are exceeded.
Intelligent software and digital integration
The ELWISOFT-Base software allows intuitive operation under Windows or Linux, real-time display of measurement results, and control via USB 3.0 or TCP/IP. Simple integration into existing systems or Industry 4.0 architectures is possible via JSON protocol.
Applications
- Alignment and adjustment of optical beam axes
- Adjustment of mirrors, beam splitters, lenses, prisms
- Construction and pre-setting of laser systems
