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

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
