Optical system design of solar simulator for testing meteorological radiation instrument

A multifunction meteorological radiation measuring and testing system is composed of the solar simulator and the multi-dimensional automatic detection platform, in order to meet the property testing requirements of the solar total radiometer. This test mainly designed the optical system design of the solar simulator, the optical system mainly consists of xenon light source, ellipsoidal condenser and optical integrator and collimating lens, the irradiation non-uniformity is ±1%, the beam collimating angle is±1.5°, The system used a design project of coaxial transmission-type and collimating optical system, after finishing the design, it optimized designed the total optical system, the results show that the aberration is adjust well, the irradiation non-uniformity is less than ±1%, the collimating error is within permitted, meeting the index requirements of verification system.
