Microsoft HoloLens 2 - Mixed Reality Smart Glasses

The Microsoft HoloLens 2 is a professional mixed reality headset designed to deliver immersive holographic experiences for enterprise, engineering, healthcare, manufacturing, education, and remote collaboration. Advanced see-through waveguide optics are combined with high-resolution 2K 3:2 light engines to create realistic holograms that blend naturally with the physical environment. Eye-based rendering technology is utilized to optimize holographic visuals according to the user's eye position, while an ergonomic design provides comfortable extended wear, even over most prescription glasses.

Powerful spatial computing performance is enabled by the Qualcomm Snapdragon 850 Compute Platform together with a second-generation custom Holographic Processing Unit (HPU). Natural interaction is achieved through fully articulated two-hand tracking, real-time eye tracking, voice commands, and enterprise-grade Windows Hello iris recognition. Real-time spatial mapping, world-scale positional tracking, and Mixed Reality Capture allow digital content to be seamlessly integrated into real-world environments, making the headset ideal for training, visualization, remote assistance, design collaboration, and industrial workflows.
