Abstract
We present a xenon arc source-based illumination system designed to achieve high spatial uniformity and efficient light collection across a wide spectral range. The proposed optical system comprised an ellipsoid reflector, diffuser, motorized iris, and collimation lens to optimize beam homogenization. Non-sequential ray-tracing simulations were performed to evaluate angular irradiation distributions of various diffusers and the overall beam profile uniformity. The system was experimentally implemented using a fused silica holographic diffuser optimized for high-power operation, with a motorized iris enabling precise control of light intensity. The resulting beam profile exhibited a well-defined flat-top shape, with a beam uniformity of approximately 95% evaluated according to the ISO 13694 standard. The developed illumination system demonstrated its ability to produce highly uniform illumination, suitable for various optical applications including spectroscopy, precision measurement, and optical imaging.
