The application scope of free-form surface solutions is very wide, covering multiple fields, including AR/VR glasses, automotive optics, LED lighting, etc.
AR/VR glasses
In AR/VR glasses, free-form surface solutions are mainly used in the design of optical modules. For example, the free-form surface diamond AR optical module released by Nadejia successfully reduced the lens thickness to less than 10mm and the module product thickness to less than 14mm, which greatly reduced the thickness of the AR/MR machine from the current approximately 25mm to less than 17mm by 32%, greatly improving the wearing comfort . In addition, the free-form surface solution also has high light energy utilization and transmittance, which can effectively reduce the power consumption of the whole machine and improve the endurance .
Automotive optics
In automotive optics, free-form surface design is widely used in head-up displays (HUD), smart headlights, projection lights, automotive lenses, smart cockpits, and automotive lidars and other fields 2. Free-form surfaces can accurately control light distribution, solve the asymmetric aberration problem caused by off-axis reflection, and improve the performance and reliability of optical systems .
LED lighting
In LED lighting, free-form surface design is used for lighting applications in street lamps, car lamps, and machine vision. By designing free-form surfaces, light with a specific shape or illumination distribution can be generated to meet different lighting needs.
