OptiTrack SlimX 120
  • OptiTrack SlimX 120

    Maximum Accuracy. Longest Range. Highest Resolution. When your application requires our class-leading 3D motion measurement precision in a very large volume, while remaining nearly invisible to casual onlookers, nothing compares with the accuracy and reliability of the SlimX 120.



    • Long Range Performance. The PrimeX and SlimX cameras offer OptiTrack's longest camera-to-marker range for Passive and Active markers.


    • Small footprint, lightweight. The SlimX 120’s shallow profile, light weight and invisible IR illumination are perfect for applications which require a discreet tracking system such as location-based virtual reality and cinematic virtual production .


    • Our highest-resolution cameras enable users to track smaller markers that are both closer to each other, and farther away from the cameras.


    • SlimX equals precision. SlimX cameras are designed and manufactured in-house at OptiTrack’s headquarters in Oregon to ensure our exacting quality standards are met.


    • Mix and match cameras. Systems can pair SlimX 120 cameras with any other PrimeX or Prime Color camera


    • High frame rate capture. The SlimX 120's 300 FPS capture rate and image stopping global shutter can be used when your application requires Prime Series precision for movement speeds above 150mph.


    • “Fast glass” lens. We custom design our own super low distortion, “fast glass” lenses for optimal marker tracking.
