Automotive heads-up displays (HUDs) use freeform LGPs to project 10°×5° virtual images. These complex surfaces, designed via NURBS modeling, eliminate ghosting effects caused by windshields.

UV-C LGPs for sterilization emit 265nm light with 80% uniformity. By integrating CsBr phosphors, they achieve 99.9% bacterial reduction in 5 minutes—critical for medical equipment.

Agricultural growth chambers employ tunable-spectrum LGPs to mimic sunlight. These adjust red:blue ratios during photoperiods, accelerating crop growth by 30%.

Underwater imaging systems use polarization-preserving LGPs to reduce backscatter. These maintain 85% contrast at 5m depth, aiding marine biology research.
