NDI Radix Lens

A wipeable retro-reflective lens for use with optical measurement applications.

Smooth Plastic Surface for Harsh Environments

The Radix™ Lens is a retro-reflective passive lens that can be integrated into OEM surgical instruments for use with the Polaris® family of optical navigation solutions to pinpoint instrument positions.

The Radix Lens features a smooth plastic surface that makes it less susceptible to liquid and particulate contamination and less prone to accuracy degradation.

Radix Lens Features:

  • Facilitates accurate optical tracking in harsh environments
  • Solid contamination is easy to identify and remove, resulting in better tracking recovery
  • Partial occlusions have minimal impact on tracking performance
  • Minimizes interruption to surgical workflow
  • Low profile marker eliminates marker-to-marker interference on planar, multi-marker tools

Resistant to Partial Occlusions

As a benefit of its form factor, the Radix Lens is inherently resistant to partial occlusions. An occlusion that partially covers one side of the lens will be reflected on the opposite side. Due to the resulting symmetrical occlusion, the marker centroid is still tracked accurately. The Radix Lens has a viewing angle of ±60°, which ensures it is readily “seen” (detected) by the Polaris® optical tracker within the measurement volume.

Radix Occlusion

Reduced Marker Interference

The Radix Lens alleviates possible marker-to-marker interference on OEM surgical instruments by way of its low marker profile. Radix Lenses and passive marker spheres can be used on separate tools during the same procedure. For example, Radix Lenses could be attached to a patient reference array or the base of an OEM surgical robotic to track its relative position, while passive marker spheres are attached to a handheld OEM surgical instrument.*
