Key Technology

Advanced Algorithms

With advanced algorithm and using free-form aspherical optical design we can effectively use the etendue of LED light source to achieve world-class light efficiency and lumen output. With machine learning algorithm, we can provide intelligent light pattern for machine vision surface defect inspection in intelligent manufacturing.

Patented Technology

Proprietary patents based on etendue match and remote phosphor conversion to achieve optimal brightness from high brightness LED, and on multi-channels architectures to achieve ultra-high brightness light engine. Patented technology can provide >20% more lumen output than conventional technology.

Ultra-short Projection Lens

Have low F/# ultra-short throw projection technology to reach throw ratio less than 0.35 with free-form technology, odd polynomial reflector and advanced architecture, which allows the projector much closer to the screen, even for big screen projection.
