A black background with a soft gradient of dark purple fading in from the bottom corners, creating a subtle and mysterious glow effect—perfect for showcasing low latency tracking visuals.

Navex™

Retro-reflective disks for high accuracy

A swirling, wave-like formation of glowing blue dots on a black background, resembling spherical fiducials in a digital or abstract 3D energy field.

Navex

Atracsys high-accuracy passive technology

Navex™ patented technology combines two key components to ensure ease of use and optimal 6D pose calculation: a high-precision marker shield made from Carbon Fiber/PEEK, and replaceable reflective disks. The disks are clipped onto the rear side of the shield, allowing tracking accuracy to depend solely on the exceptional precision of the shield’s manufacturing.

Main features

Five black medical devices with circular pads, joints, and flat fiducials for tracking are arranged on a light gray background. One device features an extended metal rod. All devices are labeled Akreosys.

Navex™ markers are thoughtfully engineered with surgical environments in mind and are readily available off-the-shelf for engineering development and system integration in the form of five distinct high accuracy marker geometries
