Abstract

With the development of infrared lighting technology, it is necessary to design infrared lighting systems for different lighting purposes. This paper presents a design method for the high-power infrared optical system. In this design, the system is composed of the high-power infrared laser diode light source array and the freeform surface lens array. The light source has a power of 125 W and a divergent angle of 10°×25°. The collimation system is designed for the light source, which reaches an energy utilization of 95% and a divergent angle of 0.5°. The system can be adapted to remote night-vision monitoring sites.

Keywords

High-power, Small divergent angle, High irradiance, Remote lighting.
