Precision Active tracking. Featuring a discreet profile and black matte finish, it excels in virtual reality, Virtual production sets, ground truth for robotics and more.
SlimX 41 - Content - Range - Media
Incredible Range. The Slimx 41 has an active marker range of more than 150’ (45m) with Active markers, all with discrete infrared wavelengths for 3D motion tracking in moderately-sized spaces.
SlimX 41 - Content - Lightweight - Media
PrimeX 41 compared to the SlimX 41
Small footprint, lightweight. The Slimx 41’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.
SlimX 120 - Content - Precision - Media
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. We design lenses with low-distortion and true 10-bit grayscale depth sensor processing which reduces noise and improves precision—resulting in perfectly crisp images, better centroids and better 3D accuracy.
OptiTrack family of cameras front view
Mix and match cameras. Systems can pair Slimx 41 cameras with any other Slimx, Primex or Prime cameras to create the optimal infrared configuration for any use case and deliver the highest 3D tracking accuracy to any environment.
Prime Lens
“Fast glass” lens. We custom design our own super low distortion, “fast glass” lenses for optimal marker tracking. The Slimx 41’s standard 12mm lens is treated with a wide band anti-reflective coating, which dramatically increases light transmission to the imager, yielding larger volumes and more precise 3D data.
Choose your lens & Field of View. For volumes of different shapes and sizes, the Slimx 41 is available with a standard 12mm lens with a 51° x 51° Field of View (FOV), or optional 8.9mm lens with a wider 65° x 65° FOV, 16mm lens with a 39° x 39° FOV, or 25mm lens with a 25° x 25° FOV.
SlimX 41 - Content - Status - Media
On-camera status indicator. Slimx cameras can keep users informed with definable color LED indicator. Recording a performance? Everyone on set knows the system is recording. Select a camera? It instantly changes color. Have your own idea? Simple software controls help you make it so.
SlimX 41 - Content - Reference - Media
Full resolution grayscale reference video. All Slimx cameras can be used as a reference video source - with synchronized, calibrated 3D overlay. Deliver and/or record full resolution, full frame rate video with 3D overlay of markers, rigid bodies, skeletons, etc.
Global - Sync - Media
External sync in/out, Genlock, and Time Code. Synchronize any SlimX, Prime and PrimeX cameras to any signal or source with the 
eSync 2
 with all the functionality and flexibility you’d expect with a professional tracking system. Cameras sync to dozens of sources including a professional cameras’ Genlock signal, where record and other event triggering can be managed from general purpose inputs and software commands.
Use the sync output signal as a master or to trigger force plates, EMGs and National Instrument DAQs for flexible yet precise hardware synchronization. Highly accurate frame timing can also be achieved with SMTPE Time Code for ease in editing and logging. OptiTrack’s free and open SDK allows for further customization within the timing protocols.
Global - Configuration - Media
Expert system configuration for any space. OptiTrack has built over 30,000 tracking systems in areas of all shapes and sizes. Our experts can help guide you on the most economical and suitable tracking system for your needs—for today and the future.

It's more than just cameras. Slimx cameras work hand-in-hand with OptiTrack’s Motive 3D motion capture software featuring Trained Markersets, Continuous Calibration, Skeletal Solver and more. The Slimx cameras and
Motive
enable users to see and analyze tracking data to inform everything from robotics and movement sciences to video game animation, cinematic virtual production and location-based virtual reality.
OEM & computer vision Integration. Incorporate Slimx 41 cameras into OEM tracking or computer vision applications via the free 
SDK
, a C/C++ interface for control of and access to raw camera frames, image processing modes, camera settings, 2D object data, camera synchronization and all 3D data.

Footnotes
1. 3D accuracy referenced is typical for a 30'×30' (9m×9m) tracking area. Range is estimated using a 14 mm marker with cameras at an exposure of 800, gain of 6, and the lowest f-stop.
