利用自由曲面设计并结合斯涅耳定律以及能量守恒定律，设计出一款能实现大面积均匀光斑的透镜组。该透镜组由一块次透镜和一块主透镜组成，其中次透镜对LED发光角进行收缩来减小透镜组结构，而主透镜对能量进行调控来实现均匀度调节。通过蒙特卡洛光线追迹模拟仿真，单个透镜组在接收面呈现方形均匀光斑，有效辐射通量比达到95。5%，均匀度达到95。7%，表明该透镜组具有良好的有效辐射通量比和均匀度;而透镜组阵列在接收面同样呈现方形均匀光斑，有效光通量比和均匀度均大于95%，表明透镜组阵列能够耦合多颗LED面阵列扩展光源，实现更高光功率的均匀光斑，可以用于基于荧光反向测量装置中大功率光源等应用场景。
Lens set design with array editability for extended light sources
A lens set that can achieve large-area uniform light spot based on LED extended light source is designed by means of freeform surface method in combination with Snell's law and energy conservation.The lens set consists of a primary lens and a secondary lens.The primary lens regulates energy to achieve uniformity adjustment,while the secondary lens shrinks the LED luminous angle to reduce the lens set structure.The Monte Carlo ray-tracing simulation shows that a single lens set can achieve a square uniform spot on the receiving surface,with an effective light flux ratio of 95.5%and a uniformity illumination of 95.7%,indicating that the lens set equipped with LED source has excellent effective light flux ratio and illumination uniformity.While for lens array,simulation shows that it can also achieve a square uniform spot on the receiving surface,with an effective light flux ratio and uniformity greater than 95%,indicating that the lens set can be extended to the lens array adapted to planner multi-LED extended source.The results show that the designed lens set and lens array have promising potential applications in satisfying high-power light sources of the fluorescence-based inverse measurement devices.
