free Stage

The free Stage was developed for quality conscious audiologists and is the ideal solution for trendoriented shops. The system-independent scanner for digitizing ear impressions can be set up effortlessly at any workstation with its slim design, turning it into an eye-catcher.

The contemporary design of the 3D scanner combines an elegant look with a robust construction. The ergonomic shape of the scanner, achieved by deliberately avoiding a housing lid, simplifies the work processes and allows its users to share the
impressive experience of the entire scanning process with their customers.

With the innovative touch sensor, you can start the scanning process directly on the scanner, saving valuable time. The consistently good quality of the materials used for production is always the most important premise for smart optics products.

Our audiology products mono Scan, duo Scan, free Stage and ds Production are 3D scanners for the digitization of ear impressions, precisely tailored to your specific needs. As a HIMSA member company, smart optics equips all scanners with a Noah interface as a matter of course, allowing the scanners’ software to be integrated into your Noah system.
