Incredible Range
The Slimx41 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.

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 .

“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.
On-camera status indicator
Slimx cameras can keep users informed with definable color LED indicator rings surrounding the lens. 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.

Powerful on-board image processing
All OptiTrack cameras feature integrated image processing. The algorithms which identify markers and marker centers, and the sequence of data delivery are important steps to achieve both world leading accuracy and low latency.
Industry-Leading Precision
Our 3D precision is the best in the business, outperforming even the highest-resolution competition—which is why Activision selected OptiTrack to build the largest and most accurate performance capture stage in existence.
Slimx is Feature Packed
All Slimx cameras can be used as a reference video source - with synchronized, calibrated overlay. Deliver and/or record full resolution, full frame rate video with 3D overlay of markers, rigid bodies, skeletons, etc.


Mix and Match Cameras
OptiTrack cameras work together seamlessly to build the perfect motion capture system for any use case.

Easy set-up
Compact, high-quality grayscale video enables image preview with multiple cameras, simultaneously—an indispensable tool for camera aiming and focusing during rig setup and calibration.
Zero Drift. Pure Precision.
Motive calibrates automatically and continuously with data collected during normal use of the system. No longer does your calibration degrade over time with changing temperatures or challenging building movement—it is always a “fresh” calibration.
Motive is behind every seamless workflow
OptiTrack’s Motive software delivers speed, precision, and ease of use, streamlining everything from calibration to real-time streaming, while tools like Aim Assist and auto-masking make even large system setups simple for one person.
