Passive Marker Shields: Reflective Spheres

Our optical devices can track any passive reflective instruments and markers available on the market. We also provide our own passive instruments designed and manufactured using the best available materials (stainless steel, titanium, carbon) for a higher tip precision. Selected models can be sterilized in an autoclave, are medically certified and bio-compatible. Multiple fixing points, clamps and other accessories make it easy to fix the disks or spheres markers.

Passive instruments and markers with reflective spheres – Atracsys proposes a portfolio of different high-quality markers with unique geometries. The geometry of our markers is pre-integrated into the provided SDK, so no configuration is required to use them. Please contact our sales team for further information on availability and lead time of the markers.
