Retro-Reflective Markers and Accessories
For Passive Optical Motion Capture Systems
B&L Engineering manufactures passive retro-reflective markers, marker clusters, and accessories for passive optical motion capture applications. Small facial markers are used in the entertainment industry for motion pictures and video. Medium and large markers are used by researchers and clinicians world-wide in medical research and sports performance applications. Pearl Markers™ are made with machined hemispheres; each covered with a single layer of 3M’s most reflective material improving the spherical accuracy and identification of the centroid at greater distances and lower exposure thresholds. Our Super Soft Markers™ provide safety and comfort for actors during contact activities. They are molded with a tough, integral flexible base that will not separate from the soft spherical marker. Velcro® hook is attached to the bottom of the base for easy attachment to body suits. Large colored Velcro patches provide attachment security and easy actor identification.
All markers are lightweight and covered with

Marker Clusters
Ideal for Biomechanics Research Software such as Visual3D™
Marker Clusters are thin, lightweight rigid curved and flat plates and may be ordered with either Traditional Markers or Pearl Markers. Multiple M4 threaded holes are provided to easily re-position the markers for automatic software identification. The markers for the clusters are provided with M4 studs for easy attachment to the plates. The Velcro® backing easily attaches to Fabrifoam® or neoprene limb wraps for each body segment. Marker Clusters are available as complete sets or individually for the heel (2 sizes), foot, shank, thigh, forearm, upper arm, lower back, upper back and headband as well as custom sizes to meet your requirements.
