Freeform surface solutions play an important role in many fields, mainly reflected in the following aspects:
Optical Design: Freeform surfaces have significant advantages in optical design. It can achieve precise control of light, optimize aberration correction, and improve the performance of the optical system through a high degree of freedom design. For example, in imaging optics, free-form surfaces can reduce the projection distance of the projector and achieve compact design; in non-imaging optics, free-form surfaces can eliminate spherical aberration, improve concentration rate, and optimize energy distribution.
Automotive Industry: In the automotive industry, free-form surface solutions are widely used in automotive optical systems, such as head-up displays, smart headlights, projector lights, automotive lenses, smart cockpits, and automotive lidar. The free-form surface design can provide a compact structure and precise light path control, significantly improving driving comfort and safety.
Processing Challenges and Solutions: Although free-form surfaces have great advantages in design, their processing faces huge challenges. Free-form surfaces have complex shapes and large curvature changes, making it difficult for traditional processing methods to meet high-precision requirements. To solve this problem, advanced manufacturing technologies such as high-precision CNC machining and nano-optical machining are widely used. Yiguang Technology has developed an intelligent adaptive error compensation algorithm to effectively suppress errors during the processing process, significantly improve processing accuracy, and ensure high-quality production of free-form surface products.
