Eye Tracking Interaction

Headset IR LEDs deliver uniform illumination via hemispherical lenses; camera-side ball lenses capture corneal reflections and pupil positions for real-time gaze tracking, enabling foveated rendering and lower compute load — a core MR spatial interaction feature. Collimating lenses enable optical path folding to reduce optical length, supporting lightweight headsets and better comfort.

Waveguide Near-Eye Display

Diffractive waveguide couplers integrate micro collimating lenses to boost light efficiency and uniformity, enabling thin, transparent large-FOV AR displays — the mainstream solution for consumer AR glasses. Ball relay lenses correct field curvature and match waveguide incidence angles; hemispherical exit pupil expanders enlarge eye boxes, accommodate varying IPD and reduce edge aberrations.

Spatial Depth Sensing

Structured light modules collimate laser spots via collimating lenses; ToF receivers use ball lenses to focus returns and build 3D depth maps for virtual-real interaction — a core spatial computing capability. Collimating lenses generate custom speckle patterns for higher depth map density; hemispherical protective windows with IR filtering suppress ambient light for stable sensing.

Pancake Virtual Image Distance Adjustment

In zoom modules, collimating and ball lenses form an adjustable Pancake folded optical path. Real-time image distance adjustment via LC or mechanical movement mitigates the vergence-accommodation conflict, a key premium lightweight VR/MR solution. Hemispherical fixed groups compensate for zoom aberrations; collimating lenses enable path folding for enhanced spatial immersion.

Facial Expression Capture

Multi-view IR cameras with micro ball lenses capture mouth and cheek micro-movements, enabling real-time digital human expression replication for metaverse social and AI avatar applications. Hemispherical diffusers deliver uniform facial IR illumination, eliminating shadow dead zones; collimating lenses ensure low short-range distortion for precise expression tracking.

VST See-Through & Spatial Recognition

3D face recognition solutions use collimating lenses to project structured spots for seamless identity verification. VST see-through systems achieve precise virtual-real alignment via lens assemblies — a core MR fusion capability. Hemispherical lenses enable wide-field IR flood illumination for multi-scenario recognition; collimating lenses shrink telephoto modules for narrow-bezel glasses, balancing safety and aesthetics.
