Exceptional Measurement Accuracy and Reliability in a Compact Size NDI’s compact optical tracker, the Polaris Lyra, is equipped with a small footprint, short stand-off, and a wide measurement volume, making it the ideal solution for applications focused on an individual body segment. Low data latency, a high measurement rate, and high accuracy add to the trusted reliability offered by the Polaris® suite of products. Exceptional Accuracy and Performance The Polaris Lyra tracks 6D tool positions with sub-millimetre measurement accuracy and repeatability. OEM surgical tool movements are precisely tracked and localized, with a measurement rate up to 125 Hz. Optimized Measurement Volume The measurement volume is optimized for targeted tool tracking within localized areas. Polaris Lyra tool geometries are correspondingly reduced, which allows for lighter and more ergonomic OEM instruments that support very precise movements. Compact Hardware Design The Polaris Lyra features a compact form factor and weighs less than 1.0 kg. The short stand-off allows the camera to be mounted close to the application area. Its portable design is enhanced with a pre-calibrated measurement volume and quick system start-up.
