Fraunhofer Institute for Applied Optics and Precision Engineering IOF
Motivation
The demand for optomechanical systems for laser beam deflection has been constantly rising in recent years. Reflection and transmission optics with ever higher speeds are being operated. The consequence of this is growing expectations on service lives and accuracy. By linking conventional manufacturing processes with the benefits of ultra-precision processing, rotation scanners with high accuracy and precise running behavior can be produced.
Benefits
- Air bearing ensures high running accuracy and deflection quality
- Self-centering with spherical bearing principle
- Static and dynamic applications up to 60000 min-1 can be realized
- Diamond-processed mirrors with optical quality
- Thermal stability with αmin-materials
- Maintenance-free, no-wear and low-noise operation
- Long service life
Our work
