Difference between imaging optical design and non-imaging optical design

The difference between imaging optical design and non-imaging optical design;

1. Imaging optics focuses on imaging quality, while non-imaging optics focuses on energy collection rate.

2. Free-form surfaces were first used for solar energy collection in photovoltaic systems, and the lighting system is the reverse process of photovoltaic systems, which is essentially the same.

3. In the imaging system, this technology can correct aberration, improve imaging quality and reduce the number and weight of system units.

4. In the design of high-performance lighting system, this technology can not only effectively improve the utilization rate of light energy, but also eliminate the strict requirement of lighting directivity, providing great design freedom.
